- INTRODUCTION
The reduction of noise and vibration has become very important :
• The need to improve conditions makes it essential.
• The increasing mechanisation of industrial and domestic activities make it necessary.
• The lightness and increasing complexity of equipment demand it.
The following pages are dedicated to protection against vibrations and shock. They offerdesign engineers the means to resolve isolation problems using elastomer alone or elastomerbonded to metal supports.The first few pages start, therefore, with a summary of definitions and an explanation of theterminology used as well as the principal formulae on which suspension calculations are based.The design of a flexible mounting system is a major undertaking and is the subject of a specialsection which gives the principles used to select a mounting according to its size,characteristics, type and applications.
Warning : solving flexible mounting system problems very often requires the services of aspecialist and we advise, very strongly, that if a simple solution cannot be found, then ourTechnical Services should be consulted.

- DEFINITIONS
II.1.1 - Properties
- Flexible mountings are components which exhibit both flexibility and damping, at the sametime and to varying degrees.
• Flexibility- Flexibility is the ability of the mounting to deform and recover, with an amplitudeapproximately proportional to the load.
• DampingDamping is a braking force the most important effect of which is the reduction of oscillations.There are essentially two types of damping :- Constant friction (dry friction) which, for a given setting, provides a constant braking forceindependent of the movement. For there to be movement, it is, therefore, necessary to apply aforce at least as great as the frictional force.- Viscous damping (such as that provided by hydraulic dampers) which provides a brakingforce proportional to the instantaneous velocity of the suspended part relative to the fixed part.Viscous damping is, therefore, essentially dynamic : it does not affect the position of staticequilibrium.
II.1.2 - Environmental conditions
Most of the standard mountings are made of natural rubber which has been chosen because ofits good dynamic properties.Under normal operating conditions, these rubber compounds guarantee stability over longperiods and, in particular, limited creep.The following operating conditions are considered abnormal :
• temperatures greater than 70°C,• prolonged contact with corrosive liquids,• prolonged contact with acids or alkalis,• aggresive environment (oils, fuels),• corrosive gases (ozone, chlorine...).
Using a mounting unintentionally under such conditions can lead to premature ageing,degradation or even destruction of the rubber.An abnormally agressive environment can, in particular, increase the deformation of themounting (creep).
PAULSTRA flexible mountings may be made using various special compounds that arehighly resistant and able to withstand the abnormal conditions described above.Our Technical Services are at your disposal to reply to any queries about the properties ofparticular compounds.
II.1.3 - Elastomeric flexible mountings
Mountings using natural or synthetic elastomers always provide a combination of pure elasticityand viscous damping. Although commonly used, the term “shock absorbers” is completelyincorrect. The two characteristics, flexibility and damping, are, in fact, essentially different : arubber mounting may be compared to a car suspension where the two functions are providedby different components working in parallel :
• true elastic suspension provided by springs,• damping provided by hydraulic damping (shock absorbers).
A flexible mounting using rubber = a spring + a damper.

II.1 - FLEXIBLE MOUNTINGS

A machine is suspended elastically by placing flexible mountings between the machine and itsseatings (floor, slab, chassis, etc.). The type of mounting, its number, distribution, positioningand individual characteristics, depend on the overall characteristics required by the suspensionto give the desired result.The most common problems are those where vibration determines the essential characteristicsof the suspension. It is necessary, therefore, to start with a presentation of the terminology anda review of the most important definitions and principles.
II.2.1 - Vibration theory conceptsA machine, suspended elastically, vibrates when it is subject to periodic alternate influenceswhich produce oscillations of greater or lesser amplitude.There are two main modes of vibration :• Natural or free vibration, which is the vibration of the machine that occurs when it is released
after having been displaced from its position of equilibrium,• Forced vibration, which is imposed on the machine, either by its own operation, or by
influences from its surrounding.
• Degrees of freedomThe number of degrees of freedom is the number of independent parameters which determinethe position of the machine at any given time.Degrees of freedom of movement :• Linear movement parallel to a given axis (the independent parameter is the displacement
along the axis),• Rotation about a given axis (the independent parameter is the angle of rotation about the
axis).
• Vibrations with only one degree of freedomThe following discussion applies to vibrations with only one degree of freedom : a linearvibration parallel to a fixed axis.• Periodic vibration :- Frequency : Number of complete cycles in a unit of time.
N = Number of cycles per minute.n = Number of cycles per second (Hertz).
- Period : Duration of one cycle.1
T = ___ (seconds)n
2π- Angular frequency : ω = 2π n = ____ (radians per second).

II.1.4 - Characteristics of elastomeric flexible mountings• Elastic propertiesThese are the parameters which define the ability of the mounting to be deformed in variousdirections.- The linear stiffness Kx, along the axis Gx is the ratio of the force to the correspondingdisplacement along this axis. The linear stiffness is expressed by daN/mm.The linear stiffness (Ky, Kz) for the other axes (Gy, Gz)are defined in the same way.- The torsional stiffness (Cx, Cy, Cz) about the three axes (Gx, Gy, Gz) is the ratio of the torqueto the angular displacement about the axis.The tortional stiffness is expressed in m.daN/rad.These six parameters, which are not independent of each other for a given mounting (theinterdependence changes with the shape and structure of the mounting) are proportional to theYoung’s modulus of the elastomer used in the mounting.Using these six values, it is possible to calculate the stiffness along or about any arbitrary axis.
• Damping propertiesThe most useful parameter is the “intrinsic damping factor” of the elastomer used. This will bedefined for a suspension (§ II.2.2). The intrinsic damping factor of a mounting is the same as thatof the suspension.
- Maximum amplitude: The maximum offset from the equilibrium position for each cycle. For aforced vibration under constant conditions, the amplitude remains constant.
• Sinusoidal vibration x = A sin ωt (fig.1)
1 ω- Frequency n = __ = __
T 2π- Amplitude A - Instantaneous amplitude x = A Sinωt- Maximum velocity V = Aω - Instantaneous velocity v = Aω cosωt- Maximum acceleration Γ = - Aω2 - Instantaneous acceleration γ = - Aω2 Sinωt
High frequency vibrations (high ω) may, therefore, produce very high accelerations even at lowamplitudes.
II.2.2 - Characteristics of flexible mounting systems
• Elastic propertiesThese are the parameters which define the freedom of a machine to move with respect to itsseating. The movements are, usually, referred to an axis system (Gx, Gy, Gz).
In the example in figure 2:
• The origin of the axis system is at the equilibrium position of the machine’s centre of gravity.• The axes are parallel to the axes of symetry of the machine.
As for mountings, the stiffness of a suspension is defined for displacements with only onedegree of freedom relative to a fixed set of axes.

- Linear stiffness :
Kx along Gx = longitudinal movementKy along Gy = transverse movementKz along Gz = vertical movementFor each axis, the linear stiffness is the sum of the linear stiffness of all the mountings.
Kx = Σ kx Ky = Σ ky Kz = Σ kz
- Torsional stiffness :
Cx about Gx = rollCy about Gy = pitchCz about Gz = yaw
The torsional stiffness of the suspension depends on :• The individual stiffness of the mountings,• The position and orientation of the mountings with respect to the centre of gravity G of the
machine.
• Damping properties
Elastomers exhibit viscous damping, the braking force applied to an elastic suspension is R x V,where :R is the resistance,V is the relative velocity of the suspended machine at time t.
If, starting with an undamped suspension, the damping is progressively increased (with allother factors remaining constant) the amplitude of the free oscillations, starting from a giveninitial offset, die away more and more quickly.The value of damping for which the return to the equilibrium position is asymptotic(without oscillation) is called the “critical damping” and is denoted by a resistance Rc.The damping factor ε is defined for a resistance R :
Rε = ___ (ε = 1 for critical damping)Rc
When suspension is subjected to forced vibrations at a frequency ω, it has been shown that, fornatural elastomers, the product ε ω remains reasonably constant. This is equally true at theresonant frequency (see below).
ε ω = εo ωo constant (ωo : is the resonant frequency).εo being the damping factor at the resonance frequency.
It can be shown that εo is an intrinsic property of the elastomer used.
εo = intrinsic damping factor.εo of a suspension = εo of each mounting (if all mountings use the same elastomer).
• Electrical characteristics
Elastomers have an electrical resistance which varies according to their composition, hardness.As a guide, the following values have been measured for our standard elastomers.
Natural Rubber hardness 45 1013 Ohm x cm2/cmhardness 60 106 Ohm x cm2/cmhardness 75 104 Ohm x cm2/cm
We have also developed special elastomers which can have a dielectric strength greater than2,000 Volts for 1 minute.

• Creep characteristics
The following formula, which is derived from measurements on samples, gives an estimate ofthe creep for a load which compresses a Radiaflex mount by 10% of its height at a temperatureof 30°C.The creep for an actual mounting also depends equally on its shape.
Static deflection at time t = initial static deflection x (1 + Cm x f(t))where f(t) is the value of the creep from the graph below :
Creep f(t) in compression relative to the initial static deflection.
and Cm is a correction coefficient taken from the table below according to the sample material :
Note :These values are given as a guide only. Consult us for use under other conditions (temperature,complex profiles or other elastomers).
Mounting :For applications where alignment is important, to overcome the problems of initial creep of theelastomer mountings, adjustment to align the axes of shafts should be made at least two daysafter the machine has been mounted.

- FUNCTION OF A FLEXIBLEMOUNTING SYSTEM
This is the primary function of elastic suspensions where there is vibration or shock. Thecalculations presented here assume that the linear stiffness of the mountings remainsconstant. This is true for elastomeric mountings in normal conditions of use (mechanicalvibration, normal temperature).
III.2.1 - Vibrations with only one degree of freedom
The action of a flexible mounting system is very complex. To present the principles, we willstudy a simple idealised case (fig. 3).
Taking the case of a machine of mass M constrained so that it can only move in a directionparallel to the vertical axis Gz.
It is attached to its seatings by a flexible mounting S with a stiffness K along the axis Gz.
An elastic suspension allows the static load to be more evenly distributed.If a machine rests on more than three points using “rigid” mountings, it is impossible to predictthe load on each mounting and the machine could be unevenly stressed.
With elastic mountings having known stiffness, it is possible to determine (by calculation, ordirect measurement) the deflection in each mounting and thus deduce the loading and correctany imbalance.
An elastic suspension accomodates minor differences in the distance between mountings.However many mountings there are, in order to avoid excessive local stresses, a rigid assemblyrequires very close tolerances on the distance between mountings and of the mating surfacesof the machine and its seatings.
To avoid prohibitively close manufacturing tolerances, “play” is allowed in the mountings whichgives rise to the well known problems of wear and noise due to loose fixings.
Flexible mountings allow larger manufacturing tolerances without large variation in forces.
An elastic suspension can also absorb small movements due to, for example, the expansion orthe deformation of chassis, bodyshells, girders, etc.

• Free oscillation (natural frequency)a) Undamped (entirely theorical)The machine, having been displaced from its position of equilibrium by a distance A, oscillatessinusoidally.The equation of motion is: z = A sin ωo t
K ωoThe natural pulsation is ωo = √ ___ Proper frequency Fp = ____M 2π
The oscillation continues indefinitely with an amplitude A (as shown in Fig. 1 with ω replaced byωo).
b) Damped In this case, the machine oscillates about its position of equilibrium with a damped sinusoidalmotion (see Fig. 4).The equation of motion is:
-ε’oω’otz = A.e .sin ω’ot
The natural pulsation is:
Kω’o = √___ (1 - ε’2 ) = ωo √1 - ε’2
M o o
ε’o is the damping factor at the frequency ω’o.
As ε’o is very close to εo, the natural frequency may, therefore, be written as:
ω’o � ωo √1 - ε2o
For natural rubber, εo is small by comparison with 1 (from 0.02 to 0.1).ω’ο is, therefore, very close to ωo.

Attenuation 2For rubber mountings, the term 4 ε 0 is much smaller than 1. The attenuation in % is 1 - λ :

ω 2 2(ω0 ) - 1 ω(ω0 ) - 1
For a given induced frequency ω the attenuation depends on the natural frequency of thesuspension.For a particular direction, the relationship between the natural frequency, the suspension’s sub-tangent and the induced frequency are plotted on the chart fig. 6.For a particular induced frequency (for example 1500 rpm) it is possible to find the sub-tangentwhich will provide an acceptable attenuation. In general, an attenuation greater than 50% isrequired. For this example, the chart indicates that an attenuation of 80% will be achieved for anatural frequency of 10 Hz (see section IV.3.1).

• Forced VibrationIf the machine is now subject to forced vertical vibration induced by a sinusoidal force offrequency ω.The inducing force is F = FM sin ωt.
- For a rigid suspension : the inducing force is transmitted directly to the structure the machineis mounted on.
ωο- For an elastic suspension with a natural frequency ωο or proper frequency Fp = ____ anddamping factor εo : 2π
When the inducing force is applied, an oscillation is induced at the natural frequency ωο whichdies away rapidly so that, after a short period, only the steady state forced vibration at frequencyω remains which transmits a sinusoidal force to the surrounding structure.The force transmitted is : F’ = F’M sin ωt.A transmission coefficient λ is defined as the ratio between the amplitude of the forcetransmitted F’M to the amplitude of the inducing force FM (or, if preferred, the force that wouldbe transmitted if the suspension was not elastic).For a mounting system using elastomeric mounts, this coefficient is :

• Practical considerationsa - Variable speed machinesIn practice, there may not be a single, well defined value for ω, as machines may have a variablespeed (variable ω).In these cases, the vibration isolation should be determined for the lowest speed.
b - Passing through resonanceAll machines must start and stop.Starting from rest to reach the speed ω (in the vibration isolation region), it is necessary to passthrough the resonant region.It is neccesary to ensure:- that the passage through resonance is as quick as possible;- that the suspension is sufficiently well damped so that the maximum force transmittedpresents no risk for the machine, the suspension or the seating.
c - Elastomeric suspensionsFor the elastomers currently used in flexible mounting systems, the intrinsic damping factor ε0lies between 0.02 and 0.1 (it can be as high as 0.2 with synthetics such as butyl rubber).- In the vibration isolation region, the formula for the transmission coefficient is simplified as, forthe values of ε0 for natural rubber, the term 4εο

a) Noise and vibrationNoise is a random vibration. It is formed by the combination of a number of uncorrelatedfundamental frequencies. Noise gives rise to sound.Airbone noise is usually treated separately from structure borne noise.Sound is associated with the disturbance of a medium (solid, liquid or gaseous). Thisdisturbance is in the form of a vibration of the molecules of the medium about their position ofequilibrium.
b) Improving acousticsAn elastic suspension affects only structure borne noise.This is a vibration of the building structure and a flexible mounting system breaks thetransmission close to the source. The resilience of the attachment reduces the forcestransmitted to the base and its vibrational energy.

As the radiation efficiency is unchanged, the improvement in terms of radiated power (acoustic)is the same as the improvement in terms of the force transmitted. The curve giving thevibrational attenuation in % may be translated into decibels.
100Attenuation in dB is 20 log _______ where E is the attenuation in % 100 - E (structure borne, not airbone noise).
The suspension of the machinery allows the adjacent room to be sound insulated and to bemade more quiet.The rigidity of the base supporting the suspended mass must always be taken into account. Asa rule, it is considered that unless the mountings are ten times more flexible than the base thechoice of suspension must be re-considered.PAULSTRA mountings may be caracterised at high frequencies.
III.2.3 - Shocks
• The nature of shocksFor a given period, the equipment is subjected to a brief, impulsory excitation. It is the mostsevere type of excitation that it may encounter during its lifetime.During the period that the excitation is applied, the speed of the equipment will vary: it issubject to acceleration and, therefore, to a force.A system that reacts slowly will not be subject to the same shock as a system that reacts quickly.It is necessary to compare the length of period that the stimulus is applied, against the naturalfrequency of the equipment.
• Types of shocksIn practice, there are two types of problems.• The equipment is subjected to shocks which are well defined by experiments, but are very
complex and not reproducible under laboratory conditions. It is, therefore, necessary todefine an equivalent shock.
• The equipment must resist shocks which are arbitrarily defined (e.g. meeting standards).A shock is defined by an excitation which varies with time: the acceleration, the speed or thedisplacement of the point where the excitation is applied. In some cases, it is better to definethe shock as the energy transferred to the equipment (e.g. vehicle impact).
• Protection against shocksThere are two principal cases to be considered:a) Limitation of the force transmitted to the equipment:This case often appears in the following form:The equipment, moving at a known speed, meets an obstacle. The force that it can withstandwithout damage is limited to a known value.A system of rubber parts, which could be the flexible mounting system of the equipment, isplaced between the equipment and the obstacle.These parts provide a constant stiffness Kz in the direction of the shock. If there is energy W tobe absorbed in the absence of damping:
1 2 WW = __ Kz s2 The maximum force FM = Kz s = ___ The maximum force is inversely
2 s proportional to the travel.
2WThe travel Z = √___ The travel is inversely proportional to the square root of the stiffness.
Kz
Note: Some systems do not have a constant stiffness, but a stiffness which increases rapidly (e.g.compression systems). It is clear that if the energy W is not absorbed before the stiffnessincreases, the maximum force will be much higher than predicted by this formula.

b) Limiting the acceleration of particular parts of the equipmentIn this case the shock must be described in terms of its potential to destroy. The efficiency ofthe protection system is measured by its ability to reduce this potential.A shock to the equipment can damage a component part if this part is induced to vibrate at anamplitude which is incompatible with its mechanical characteristics thus causing it to break.
A shock can be characterised by its action on a whole series of components.For the same shock, each component has its own specific response, which differs from onecomponent to the next.The shock spectrum is the graphical representation of the ratio of amplitude of vibration (Γ) ofthe components to the amplitude of the shock (Γ0) as function of the ratio of the duration of theshock τ to the natural frequency T of the elements.This is not a representation of the amplitude as a function of time, neither of the excitation norof the effect, but a convenient representation of the destructive power of a shock.The representation is not reversible.• It is not possible to recover the form of the shock from the spectrum.• Two different shocks may well produce the same spectrum.Take, for example, the case of shock with a semi sinusoidal acceleration.
Study of the spectrum shows that the performance of a mounting system is acceptable when itis possible to obtain a natural frequency T such as :
τ Γ__ < in which case the ratio __ is less than 1 and the component is protected.T Γο
If it is not possible, it is better to set up the flexible mounting system to avoid the region ofsignificant amplification for :
τ__ between 0.25 and 2.5T
This simple case shows the role of a flexible mounting system and the importance of knowingthe details (shock spectrum, amplitude as a function of time) and, above all, the duration of theshock.
• The role of dampingDamping can be useful in reducing rebounds and the amplitude of successive cycles ofoscillation. It is, however, important not to use just any type of damping as some can give riseto unfortunate reactions. Elastomers provide a compromise which allow the provision a highlevel of protection.

III.3.1 - Active isolation systemThis is a flexible mounting system designed to prevent a machine from transmitting itsvibrations to its seating or foundation.This is the theorical problem (with one degree of freedoom which was treated, by attenuatingthe vibration, in the preceding pages.The vibration isolation does not stop the machine from vibrating, but it reduces the transmissionof these vibrations.By comparison with a rigid suspension (which transmits the vibrations) the amplitude of themachine’s vibrations may be greater. The machine is, to an extent, freed from its fixed seating.This is the case for the automobile “floating engine” which, mounted on a flexible mountingsystem, no longer transmits its vibrations to the bodywork and the passengers due to increasedmobility under the bonnet (hood).If excessive movement cannot be tolerated, the only way to reduce it, without reducing theefficiency of the flexible mounting system, is to increase the suspended mass (ballasting).For a given excitation, the amplitude is inversely proportional to the mass.This is necessary for certain machines which produce particulary severe vibration : slow singlecylinder compressors, centrifuges, power hammers etc.These machines, are therefore, fixed rigidly to a chassis or heavy slabs and the whole assemblyis suspended.Increasing the suspended mass allows good vibration isolation with limited vibration of thesuspended assembly.It is worthwhile suspending complete assemblies rather than individual machines : generatingsets, motor/compressor units, motor/pump units.
• Important noteTwo points must always be borne in mind when designing equipment :• Firstly, that a high level of protection requires great flexibility which requires considerable
clearance between the equipment and its surrounding.• Secondly, that the equipment will oscillate and room must be allowed for the rebound in case
of shock. Travel limiters must be positioned so that they do not impede the operation of theflexible mounting system during the shocks allowed for in the design.
A flexible mounting system using rubber protects against shock by reducing the travel andmaximum force. It is necessary to allow enough clearance for the rebound.
III.2.4 - General caseTheoretical study above is based on a very simple case :movement with only one degree of freedom (vertical) with only one excitation (also vertical)aligned with both the centre of gravity of the suspended machine and the centre of elasticity ofthe mounting system.In general, things are not so simple. The machine can move in any of the degrees of freedom(rotation or linear movement). In theory, there are as many natural frequencies as there aredegrees of freedom.These natural frequencies are not independent but are “coupled”. If one of these is excited inone degree of freedom, it can, as a result of the coupling, give rise to vibrations at the samefrequency in other degrees of freedom.To analyse the whole behaviour, the stiffness in all directions needs to be taken into accountand not just the mass of the suspended body but also the moments of inertia so that rotationalbehaviour can be evaluated.In addition there may be not one but several forced vibrations, with variable frequenciesapplied to several different points, in various directions or about various axes.Even general cases can be very complex however symmetrical structures and mountingarrangements allow the use of the single degree of freedom analysis shown above. In othercases only an in-depth study allows an effective solution to be found. Our Technical Services arethere to help you to define it.
III.3 - VARIOUS TYPES OF FLEXIBLE MOUNTINGSYSTEMS
17
III.3.2 - Passive isolation systemThis is a flexible mounting system designed to protect a non-vibrating machine from thevibrations of its surroundings.The design of a flexible mounting system for attenuating vibration, as defined above, is stillvalid. With the correct flexible mounting system, the acceleration transmitted to the machine isvery small and as it is not subject to any other excitation it remains almost stationary.The vibration of the supporting structure is almost entirely absorbed by the flexible mountings.
III.3.3 - Semi-rigid mounting systemThis is a suspension where there is no vibration isolation for a given frequency ω
ω( __ < √2 )ω0
As shown above, such a mounting system should be of no interest as it leads to an amplificationof the vibration, not an attenuation. In practice, it can, however, give reasonable performance inthe following two cases.
• CouplingIn practice, there is not just one movement. For a mounting system, several movements arepossible. In fact, as we have seen (fig. 2), a machine may have six degrees of freedom. A properstudy of a mounting system will take into account the type of excitation acting on the machineand try to arrange that it does not vibrate in all directions. However, because of constraints onmounting points, the mountings may not always be put in ideal positions : if the machine issubject to an excitation in one direction, it may, therefore, move in several directions e.g. two.These two movements are said to be “coupled”.The natural frequencies in each direction are not identical. The coupling between the twomovements has the effect of lowering the lower natural frequency and raising the higher. Insteadof having one maximum (fig. 5), the response curve has two. It is essential the excitation doesnot fall on one or the other. As it may demand an impossibly high flexibility, it is not alwayspossible to make the coupled natural frequencies sufficiently low to put the frequency of theexcitation in the vibration isolation region. On the other hand, if the two natural frequencies areplaced on either side of the frequency of the excitation, a modest attenuation may be obtained.
• HarmonicsA vibration of frequency ω is rarely “pure”. Frequently it also includes “harmonics” ; i.e.vibrations at related frequencies 2 ω, 3 ω ... Even if it is not possible to provide vibrationalisolation of the fundamental ω, it may be possible to attenuate the harmonics. This may be moreimportant as the low frequencies are often inaudible and, in addition, correspond to very smallmechanical accelerations whereas the higher frequencies are a source of noise which can beeliminated by an appropriate vibration isolator.
III. 3.4 - External connections
So far, it has been assumed that the machine is only connected to its surrounding by its flexiblemounting system.In pratice, there will be other connections, such as :• Pipework (inlet, exhaust, cooling).• Electric cables, remote controls...It is necessary to ensure, or arrange, that these external connections are sufficiently flexiblewith respect to the relative movements.This precaution will avoid :• Damage to pipework.• Reduced vibration isolation by introducing additional rigidity.• Direct transmission, via these connections, of the vibrations which have been suppressed
elsewhere.As the flexible mountings attenuate the transmission of the vibrations the machine is free tomove, be sure to leave enough clearance in all directions to allow freedom of movement.

When designing a flexible mounting system, it is essential to know, precisely the basiccharacteristics of the machine to be suspended.
It is extremely useful to have a drawing (even if it is schematic) which shows the position of thecentre of gravity and the mounting points provided.The drawing may also allow the evaluation of certain parameters which may be necessary andwhich are often unknown to either the manufacturers or the users (e.g. moments of inertia).
For passive isolation, it is necessary to obtain the maximum of information about the externalvibrations which may disturb the machine.In any case, for complex problems (oscillations in many degrees of freedom, multipleexcitation), it is advisable to consult our Technical Services.
For simple problems (one degree of freedom, or two degrees of freedom with the centre ofgravity close to the mounting plane) it is possible to design the suspension, as shown below,with a minimum of information about the machine and the disturbance.
- DESIGNING A FLEXIBLEMOUNTING SYSTEM
IV.1.1 - Ask the manufacturerIn most cases, the manufacturer of the machine should be able to supply the exact position ofthe centre of gravity as well as the weight.Consult the manufacturer.
IV.1.2 - Graphical method for finding the centre of gravity of an assemblyThis is suitable for assemblies of units for which the individual weights and centres of gravityare known.
Important notes :• Using a graphical method, it is important to represent dimensions using a well determined scale
and the weights by vertical lines whose lengths are proportional to their size (e.g. 1 cm for10 daN).
• If the centres of gravity considered in this section are not in the same vertical plane, theprocedures proposed here should be applied twice : for the front and for the side view withthe outlines corresponding to each view.

• An assembly of three or more units
Proceed, stage by stage, as described above using groups of two units or sub-assemblies withcentres of gravity and weight known or calculated.
IV.1.3 - Experimental determination of the centre of gravity of a unit
This method is used where the above two methods prove to be impossible or difficult (complexgeometry).
• Using a roller
For a given orientation (length, width and height) the centre of gravity is in the vertical planepassing through the axis of the roller when the machine is balanced. The centre of gravity is atthe intersection of the three planes thus determined.
• By “hanging”
Suspended from a cable, the centre of gravity is on the vertical dropped from the suspen-sionpoint. To find the exact centre of gravity, repeat the operation twice, using a different suspensionpoint each time.

IV.1.4 - Analytical determination of the centre of gravity ofan assembly of several masses
An assembly of several masses m1, m2, ... mn is fixed in space.It is assumed that the coordinates, within an arbitrary Cartesian set, of each mass are known.
X1 X2 Xnm1 { Y1 m2 { Y2 mn{ Yn
Z1 Z2 Zn
The mass of the assembly M = m1 + m2 + ... + mn acts at the coordinates of the centre of gravityof the whole : x, y, z
m1 x1 + m2 x2 +...+ mn xnx = _________________________M
m1 y1 + m2 y2 +...+ mn yny = _________________________M
m1 z1 + m2 z2 +...+ mn znz = _________________________M
Important note : The coordinates of the centres of gravity may be negative and must be usedwith their sign.
IV.2.2 - Number and position of the mounting points are predeterminedIn this case, it may not be possible to have the same load on each mounting.
• Four mounting pointsA, B, C and D are the mounting points,G the centre of gravityP the total weight suspendedPA, PB, PC and PD are the loads on the mounting points A, B, C and D.
m2 l2 m1 l2PA = ___ . ___ . P PB = ___ . ___ . Pb a b a
m1 l1 m2 l1PC = ___ . ___ . P PD = ___ . ___ . Pb a b a
If PA, PB, PC and PD are significantly different, it is, theoretically, necessary to choose fourdifferent mountings which will give the same deflection under the various loads.
IV.2.1 - Number and position of the mounting points are not predeterminedIn this case, the number and position of the mountings are determined in such a way that theload on each mounting is the same for all mounting points.Taking, for example, a symmetrical machine with :
G : the centre of gravityP : the weight of the machineCalculate the position of 6 mounting points such that the loadon all the mounting points is P1
P1 l’1 + P1 l’2 = P1 l1Weight
from which l1 = l’1 + l’2 and the load per point = ______6

• More than four mounting points (fig. 15)In this case it is best if the assembly is symmetrical about avertical plane. This is assumed to be true in the following.To the left of G, there are 2n identical mountings.To the right of G, there are 2p identical mountings which are,possibly, different from the 2n mountings to the left.The problem is to set the difference between the left handand right hand mountings so that the deflection under load ofthe 2n + 2p mountings are all the same.Under these conditions, all the mountings to the left of G willbe supporting the same load Q and all those to the right willbe supporting the same load R.This will give :
Q (l1 + l2 + ... + ln) = (λ1 + λ2 + ... + λp)2 nQ + 2 pR = P
From which the mountings charge is :
λ1 + λ2 + λpQ = ________________________________________ . P
2 n (λ1 + λ2 + ... + λp) + 2 p (l1 + l2 + ... + ln)
l1 + l2 + lnR = ________________________________________ . P2 n (λ1 + λ2 + ... + λp) + 2 p (l1 + l2 + ... + ln)
If Q and R are not too different, the same size mountings maybe used but with different hardness elastomers.
Example (fig.16)Taking a symmetrical machine with an offset centre of gravityG and 6 mounting pointsn = 2 et p =1.which gives :
λQ = ______________ . P
4 λ + 2 (l1 + l2)
l1 + l2R = ______________ . P4 λ + 2 (l1 + l2)
IV.2.3 - Important notes
If a single size of mounting is used, but different hardness elastomers are choosen, there is ahigh risk that the mountings may be interchanged which may degrade the attenuation of thesuspension. The machine must be mounted with great care.There are, however, benefits from using identical mountings to build a suspension. If thepredetermined mounting points of the chassis do not allow a centered suspension, the solutionis to attach these to a false chassis, as rigid as possible, to which the desired number of identicalflexible mountings are attached in the positions required. If this false chassis is a slab ofconcrete (or inertia block) the suspended mass is increased which improves the quality of thesuspension.
IV.3.1 - Deflection and sub-tangentFig. 17 is a graphical representation of the derivation of the deflection and sub-tangent from theload/deflection curve.

If the machine weighs 500 daN and λ = 0.4 m ; l1 = 0.3 m ; l2 = 0.9 m, then Q = 50 daN and R =150 daN.

For most PAULSTRA mountings, the load/deflection curve is linear in the region of static loads(fig. 18) and, as a result, the sub-tangent and the deflection are identical.
The curve in fig. 17 is typical of EVIDGOM mountings.For these it is best to work at the point of inflection of the curve where the sub-tangent is thelargest possible and so the natural frequency is as low as possible.The deflection does not indicate the amplitude of the oscillations of the machine.
IV.3.2 - Operating regions
The region OM is the static load region. The deflection is approximately proportional to theload.
In the data sheets, the coordinates of the point M are given as the NOMINAL STATIC LOAD.
The region MP is the dynamic load region corresponding to normal, repeated shocks providedthat the rate and total deflection stay within normal limits.
In the region PZ, which corresponds to exceptional, accidental shocks, the curve rises rapidly.The stiffness increases progressively which has the effect of reducing the amplitude of themovement. Note that, because of the natural damping properties of the rubber, this increasealso depends on the speed of impact.
For a given static load, the deflection corresponds to the compression of the mounting underthat load, but the stiffness about the position under load is given by the sub-tangent (theprojection of the tangent onto the axis). This is the elasticity which determines the naturalfrequency of the mounting.

IV.3.3 - Attenuation - excitation frequencyAt a given excitation frequency ω, the attenuation depends on the natural frequency ωo and thusthe sub-tangent.With most rotating machines, the excitation frequency in cycles per minute can be taken to bethe rotation speed in rpm.As indicated on the chart (fig. 6, in § III.2.1.2) for a natural frequency in a known direction, theaim is to obtain the highest possible attenuation within the constraints of the load / deflectioncharacteristics of the mountings.The deflection selected must not be so high as to be detrimental to the stability of thesuspension.If the operating point is not within the vibration isolation zone, our Technical Services should beconsulted.
IV.3.4 - Static stiffness - Dynamic stiffness - Natural frequencyWhereas deflection and sub-tangent are given by the static stiffness curve of the mounting, it’snatural frequency is linked to the dynamic stiffness. In the case of elastomeric mountings, staticand dynamic stiffness can be different.The ratio between static and dynamic stiffness depends on the input amplitude, the frequencyand the type of elastomer. Under nominal load, the natural frequency is given for indication only.For a different load, the natural frequency could be found with the following formula :
nominal loadFp (actual load) = Fp (nominal load) x √______________
actual loadThis approximate is valid only if the actual load is in the linear part of the load/deflection curve(Fig. 17 & 18).
PAULSTRA mountings are classified according to their stiffness characteristicsTherefore, after having determined the number and deflection of the mountings as describedabove, the choice of mountings depends on the direction of the excitation.• Equi-frequency mountings : the flexibility is approximately the same vertically as horizontaly.• Mountings with high axial flexibility : high axial flexibility while supporting radial loads.• Mountings with high radial flexibility : high radial flexibility while supporting axial loads.• Low frequency mountings : high sub-tangent to achieve a very low natural frequency (a few
Hertz).
IV.4.1 - Suspension for a fan• Characteristics of the equipment :- Weight : 3000 daN.- Speed of rotation : 1200 rpm.- Fan mounted on a 2.5 x 3 m chassis with no constraint on the position of the fixing points.- Known centre of gravity.Number of mountings : after trials, using successive approximation to balance the moments ofinertia, 12 mountings points were selected.Load per mounting = 3000/12 = 250 daN.Natural frequency of the mounts (see chart).For an input frequency (or speed of rotation) of 1200 rpm, the maximum natural frequency is 14 Hz.A natural frequency of 7 Hz will achieve a reasonable attenuation of about 85%.Therefore, a mounting with a natural frequency of 7 Hz under 250 daN is required.As it is a rotating machine with no special characteristics, isometric mountings are selected.The selection guide gives a PAULSTRADYN mounting with a 8 mm deflection under a 260 daNload. According to the data sheet for PAULSTRADYN mountings, the PAULSTRADYN Ø 100hardness 60 has a deflection of 7.4 mm under a load of 240 daN, which is just right.

IV.4.2 - Suspension of an engine/hydraulic pump unit mounted on an excavator
• Characteristics of the assembly :
- Weight : 1200 daN.- Speed of rotation : 1500 rpm.- Known centre of gravity.- 6 mountings points.
Load per mounting : 1200/6 = 200 daN.Deflection (see chart, fig. 5).For a frequency of 1500 rpm, a deflection of 3 mm will achieve an attenuation of approximately85 %.
The vibrations are predominantly vertical and the unit needs to be restrained laterally to copewith the movement of the excavator in operation. Mountings with dominant axial flexibility areselected.
The PAULSTRA mounting selection guide gives a STABIFLEX mounting with a deflection of5 mm for a load of 210 daN. According to the STABIFLEX mounting data sheet, the mountingrequired is a STABIFLEX 530622 hardness 45 with a square base.
• Suspension characteristics (under 1200 daN at 1500 rpm) :

Load per mounting : 400/6 = 66 daN.Deflection (see chart, fig. 5).For a frequency of 20 Hz, a deflection of 6 mm will achieve an attenuation of approximately 70%.
Mountings characteristics required :
1) mountings which will withstand the vertical load ;
2) mountings with a radial flexibility very much greater than the axial flexibility (mounting withdominant radial flexibility) ;
3) providing vibration isolation vertically (axially), which, taking account of requirement (2), willassure the horizontal vibration isolation.
The PAULSTRA mounting selection guide gives a RADIAFLEX cylindrical stud giving adeflection of 8 mm for a load of 70 daN.According to the RADIAFLEX mounting data sheet, the mounting required is a stud Ø 30 height30 mm with 2 mounting bolts (ref. 521312).The radial flexibility (shear) is considerably higher than axial flexibility (compression).

• Deflection of mountings :For a frequency of 400 rpm, the minimum deflection to be within the vibration isolation regionis 12 mm. The PAULSTRA mounting selection guide gives a low frequency mounting which canprovide sufficiently large deflections (26 mm).According to the EVIDGOM mounting data sheet, the mounting required is an EVIDGOMmounting Ø 125, height 140 mm, reference 810784 which gives a deflection of 26 mm under aload of 800 daN.
• Suspension characteristics :- 8 EVIDGOM mountings reference 810784, Ø 125 mm, height 140 mm.- Deflection 26 mm.- Attenuation 37 % (4 dB).Note : as the low frequency mountings are tall, for some applications (sideways forces) it maybe necessary to provide lateral stops.

RADIAFLEX
• Metalwork: Mild steel, plated.• Natural rubber, bonded, cylindrically shaped.• Welded fixings: 5 styles (single sided threaded stud, single sided
threaded hole, double threaded stud, double threaded holes,combination fixing).
In Europe, we often use different screw standards than our frenchstandard.
To better satisfy this need, Paulstra has created a new range TRadiaflexEurope.
This range is available with the 4 usual welded fixings and with a newfixing: the threaded hole stop.
The design of the RADIAFLEX mount gives the following basiccharacteristics:
• Radial elasticity greater than axial elasticity.• The rubber works in:
- compression (axial).- shear (radial).- compression/shear according to the fixing method.
Advantages:
• Simple to fix.• Simple and economical.• Extensive range:
- 13 stud diameters.- Several heights for each diameter.- 5 methods of fixing.
Recommendations:• Operation in shear is very useful for vibration isolation provided that
the radial forces are not too great.

STABIFLEX
The STABIFLEX mounting comprises a conical rubber section bondedbetween inner and outer metal parts.
• Centre axis with threaded hole.• Square (4 holes) or diamond base (2 holes) with clearance hole.• Bonded natural rubber, anti-slip bead.• Cup to protect the rubber and distribute the load.
The design of the STABIFLEX mounting gives the following basiccharacteristics :

S.C. MOUNTING
The S.C. mounting comprises an annular section bonded between theinner tube and outer housing.The outer housing has a mounting flange (4 different types).
The design of the S.C. mounting gives the following basic characte-ristics :
• Axial elasticity four times higher than radial elasticity.• The rubber works in shear.• Progressive buffer against shocks or accidental overload, provided
that a large metal washer is used to bear against the rubber dome.• Can be used as a fail safe assembly when fitted as in figure 1.
Advantages :• Extensive range : 3 hardnesses of rubber for 20 existing types,
allowing the mounting to be optimised as a function of the load andexciting frequency.
Recommendations :• In order not to affect the performance of the mounting system, all
external connections must be flexible.• S.C. mountings must be fitted so that the vibration input is in the axial
direction.

EVIDGOM®
The EVIDGOM mounting is formed from two thick conical membranes,joined at their bases to create a highly elastic mounting.There are three variations :
• All rubber EVIDGOM.• EVIDGOM with bonded fixing.• EVIDGOM with a diamond or square mounting plate (fixing plate
supplied as a separate kit).
The design of the EVIDGOM mounting gives the following basiccharacteristics :
• A very high axial elasticity.• Very low natural frequency (a few Hertz).• Progressive buffer against shocks or accidental overload.
Advantages :• As the load/deflection curve has a point of inflection, a suspension
may be designed to have a sub-tangent greater than the staticdeflection.
• The elastomer used provides intrinsic damping with a correspondingability to absorb energy which gives appreciable advantages overmetallic springs.
Recommendations :• The selection of a low natural frequency (large deflection) must not be
allowed to endanger the stability of the suspension (tall equipment).• In certain cases (use under maximum load) the use of side stops is
recommended.

STOPS
There are several types of stops :
• Cylindrical or DIABOLO stops.• Conical progressive stops.• LEVAFLEX progressive stops with central cavity.• EVIDGOM stops.
The design of the PAULSTRA elastic stops gives the following basiccharacteristics :
• Highly deformable allowing high energies to be absorbed.• Progressive absorption of energy due to the carefully designed
shape.
Advantages :• By comparison with rigid stops, PAULSTRA elastic stops are quiet and
avoid hammering and deterioration of equipment.
Recommendations :• The stops must be fitted so that, on impact, the axis of the stop is
perpendicular to the contact surface.• On impact, the external diameter of the stop increases : this must be
allowed for when fixing.

TRAXIFLEX
The TRAXIFLEX mounting comprises two metallic U armatures joinedby two bonded rubber blocks.It is available in two versions : male/female and female/female.
The design of the TRAXIFLEX mounting gives the following basiccharacteristics :
• Rubber works in compression-shear.• The same deflection under nominal load for all types.• Positive safety in case of elastomer failure.
Advantages :• Economic solution for suppressing structure borne noise.• Several fixing methods.• High resistance to atmospheric exposure :
- galvanised armatures- chloroprene elastomer.
• Upper metallic part is shaped to simplify orientation while fixing.• Two hardnesses of elastomer to extend the choice of mounting as a
function of load.• Filtration of vibration and the attenuation of the consequent noise.• Allows movement due to thermal expansion.

BATRA RING
The BATRA ring comprises a rubber ring bonded to two metallicwashers one with a circular groove, the other with a mating circularridge which allows BATRA rings to be mounted one on top of another.
The design of the BATRA ring gives the following basic characteristics :
• Behaviour identical to that of a metallic spring plus damper.• Robustness :
- well behaved under shock.- removal of the risks of suspension collapse.
• Flexibility easily tailored by stacking BATRA rings.• Transverse creep limited by the two bonded armatures.
BATRA rings may be used :
• For making suspensions that are very flexible vertically and alsodamped by the natural properties of the rubber (road and railvehicles).
• For making very effective anti-shock buffers (wagons, cars, gantries).For special applications, where the quantities would justify custommanufacture, it is possible to supply Special BATRA rings either withonly one bonded lower armature or “all rubber”.For special cases of shock, there are Special BATRA rings withoverlapping, non-bonded, armatures.

BECA
The BECA mounting comprises one piece elastomer bonded to a topand bottom plate.• Top plate: smooth or threaded (welded nut) hole.• Bottom plate: Fixing lugs or direct bearing on the ground.• Bonded rubber.• Domed rubber ring.• Anti-slip bead or grooved anti-slip sole.• Removable protective top cover : protects the rubber and distributes
the load.
The design of the BECA mounting gives the following basiccharacteristics :• Transverse elasticity approximately the same as the axial elasticity
(equi-frequency).• Rubber works in compression.• Progressive buffer against shocks or accidental overload.• Anti-slip (may be placed directly on the ground).Advantages :• The machine may be placed (with its mountings) directly on the
ground.• Very slim.• Speed of fixing.• Simple removal of the assembly.• Extensive range: 3 hardnesses of rubber for 6 existing sizes, allowing
the mounting to be optimised as a function of the load and stimulationfrequency.
• A choice of 3 fixing styles.Recommendations :• In order not to affect the suspension of the machine, all external
connections must be flexible.• BECA mountings can be used for fixed, well-balanced rotating
machinery, otherwise a ballasting slab should be used.(1) Natural frequencies with max/min loads, see : OPERATING CHARACTERISTICS.Nota : BECA mountings can be replaced by PAULSTRADYN mountings.

“SANDWICH”MOUNTING
The SANDWICH mounting comprises one or more layers of elastomerbonded to flat, parallel metallic plates. These mountings may becylindrical or rectangular. They are designed to withstand very highcompressive loads. The range of mechanical characteristics is gover-ned by the hardness of the rubber and the number of intermediatemetallic plates.
These mountings can support compression from 20 to 100 bars.
The metal plates usually receive a phosphate anti-corrosion treatment.
The elastomer is polychloroprene which provides a high resistance toatmospheric exposure.
The design of the SANDWICH mounting gives the following basiccharacteristics :
• Very slim.• Large surface area.• Stackable mountings.• The suspended equipment is free to move in all directions.• High ratio of axial stiffness to radial stiffness.• Very high axial loads.

AIR SPRING
The PAULSTRA air spring is a rubber-coated flexible structure seatedand sealed with internal and external steel supports.
The air spring is designed to have the following basic properties :
• Low natural frequency.• Lateral stiffness.• Adjustable height.• Withstands adverse weather conditions and temperatures from - 40°C
to + 70°C.
(1) Natural frequency with max. load, see chapter : OPERATING CHARACTERISTICS.
DESCRIPTION
OPERATION
(1) Natural frequency :1 Hz
97
The air spring must be mounted on an upper plate using a flange thesame shape as the air spring to provide a good seal. The lower part ofthe membrane may rest on a rigid support with a restraining andsealing bead.
PAULSTRA also offers a flexible mounting for the air spring to enablethe suspension to be used in non-standard applications or undertorsion.
Ask us for details of the mounting dimensions.

STRASONIC®
102
STRASONIC is a range of complex materials designed to provide thebest acoustic isolation. Their structure is based on polyurethane foamsor cellular rubber.
Their main function is to reduce airbone noise (Isolation, Absorptionand Damping) in partial or complete enclosures of machinery.
The STRASONIC material can be used in a range of applications suchas : air conditioning, pumps, presses, compressors, electric motorsdiesel engines, generator sets, gearboxes, turbines, agricultural orconstruction equipment and other machinery.
Due to their design (Sheets of 500 mm x 500 mm or 500 mm x 700 mm)they are easy to handle, light and a self adhesive side simplifies theinstallation (depending of the type of foam).

VIBMAR
The VIBMAR series has a base plate with two or four mounting holesand a tapped steel core.The elastomer is bonded to the steel.
E1N104 and E1N106 versions have a conical spring embedded in therubber.
Environmental protection is provided by painting the metal parts andby coating the elastomer with an ozone resistant compound.
These multi-axis low frequency dampers have been specially designedto protect electrical or electronic racks and marine or road transportgenerator sets (on board or not). They are cone-shaped to absorbconsiderable displacement and shocks.

ELASTOMERPLATESE3PEPL
VHDS elastomer sheet.
These sheets may be used for making grommets, washers or anti-vibration mountings for equipment.There is a wide range of VIBRACHOC moulded parts, but in certaincases, such as prototypes - undefined specification, etc, it is oftenadvantageous to determine the suspension using elastomer compo-nents cut from sheet and bonded.
• Overall tolerances:- on the lengths: ± 5%- on the thickness: ± 3%
VIBRACHOC plates should be ordered using the following reference:E3PEPL ❏ ❏ S ❏ ❏ C ❏ ❏ ❏
1 2 3
1: dimension in cm.2: grade (see. table page 126).3: thickness in 1/10 mm.
For example: E3PEPL30S55C060 =• square plate 300 X 300 mm.• 6 mm thick VHDS rubber compound.• grade 55.
For other shapes, sizes or materials, ask us for details.

SLM pneumatic mounts are made from synthetic rubber and arelaterally reinforced with steel springs.
The base plate is bored with 4 smooth holes to allow a possible fixingon the ground and the valve allows to inflate the mount in the same wayas an automobile tyre.
• Elastomer body (temperature range -30°C à +180°C) resistant tooils, the majority of solvents and natural ageing.
• The top and bottom plates are available in both steel and aluminium.

PNEUMATIC MOUNTS SLM
DESCRIPTION
OPERATION
Natural frequency:3 to 5 Hz
(1)
APPLICATIONS• Industrial plant, compressors, conveyors, vacuum pumps, generators,
air-conditioners, diesel engines, ventilators, presses with fast cycle,machine tools.
• Metrology: measuring apparatus sensitive to the external distur-bances, optical instruments, etc.
(1) Natural frequencies with max/min loads, see : OPERATING CHARACTERISTICS.
The design of SLM mounts gives the following basics characteristics:
• In the event of loss of pressure, the machine will rest on the elastomerbody. The load capacity of the mounting remains unchanged.
• The ratio of horizontal rigidity and vertical rigidity of the SLM is 1:1,which allows excellent stability.
Advantages:
• Eight sizes, capacity range of 10 daN to 10000 daN.• Allow you to level the machine gradually while varying the air
pressure.• Possibility of varying the natural frequency, by varying the air
pressure.

Recommendations:
• The machine must rest on the supports before they are inflated to the level indicated ondimension " G ".
• Before any diassembling, the SLM mount must be deflated.• The surface of the machine must completely cover the surface (Ø F) of the mount. If it is not
possible, use a separate plate (thickness between 5 and 10 mm, according to the load) anddiameter equal to F + 10 mm. This is to obtain a base on the full surface. It is required for assembly and in the event of an air leakage.
• If necessary, it is possible to fix the supports using the four smooth holes on the bed plate.• Make sure care that the valves are protected.• Never overload the mounts. Always use the recommended load capabilities.
