Design of Go-Kart

Chassis analysis of Go-Kart -Mr. B.V.Suresh

The team IKSHUNETRA intends to design and manufacture a safe durable, reliable and high performance Go-kart, the main aim is to win SKDC 2017 by manufacturing not only the best performance Go-kart but also the robust and economical one to comply the rulebook of SKDC 2017.

The primary objective of this team is as follows: 1. Endurance 2. Safety and Ergonomics 3. Market availability 4. Cost of the components 5. Standardization and Serviceability 6. Maneuverability 7. Safety engineering practices. To achieve our goals the team has been divided into core groups responsible for the design and optimization of major sub-systems which were later integrated into the final blueprint. As this championship being a design challenge, the team being new to this championship, had a great platform to enhance the good engineering approach and practice. The team thereby comes up with a successful design with few innovations that come to light in this event.

The report provides detail explanation about the vehicle and its internal data. The report covers validating theoretical calculations, and simulations and optimized results.

MATERIAL

CHASSIS

The frame is designed to meet the technical requirements of competition the objective of the chassis is to a driver, efficiently and safely. Principal aspects of the implementations included driver safety, drive train integration, and structural weight, and operator ergonomic. The number one priority in chassis design was driver safety. By the competition rules and Finite Element Analysis (FEA), the design assured.

Design: The main component of the frame are divided into two major parts

first the point block for the steering and seat positions etc. and second rear block for transmission and brake assembly. Both the blocks are separated by the Firewall. The frame model can be viewed as shown below. Before Impact

FRAME DESIGN CONSIDERATIONS: A) Weight: The frame is one of the largest and heaviest components of the car and which requires special attention was place on the vehicles’ frame weight. Once baseline safety design requirements were met, FEA aided the material decision making process. FEA specifically helped to determine whether a member was under high or low stress, in the scenario discussed previously, making the chassis design process efficient and effective. Chassis members were made out of steel, this material was chosen because of its weight reduction capability and beneficial material properties, as was stated previously. Through accurately determining stresses on the chassis in different scenarios. The final weight of chassis was measured on software is 57.459 kg and the gross weight of the vehicle along with the driver is estimated to be 200 kg. Aesthetic : Aesthetically, the roll cage design is improved by the use of more rounded corners, than the straight. The unique use of rounded corners allows for a more pleasing look to the vehicle’s body as well as reduced number of welded joints. The use of continuous bended pipes also reduced the no of joints the lack of sharp edges on the roll cage allows for the design of more streamlined body panels which not only took smoother, but may also have a positive effect on the overall aerodynamic drag forces.

Manufacturability: All design work for the go kart championship has done in the Auto Desk Fusion 360. Using this program to produce three-dimensional model allowed easy revision of prebuilt designs, and gave design team members a visual picture of what the frame would look like. After the design of the frame was finalized, a list of required support member was created and the frame model was modified. The design for manufacturability, ergonomics and aesthetics for the roll cage are favorable for its reproduction, serviceability and comfort. The material selected STEEL has good manufacturability qualities. By implementing bends into the design of the frame, the number of cuts and welds were decreased. Decreasing the number of cuts and welds lowers the production cost and increases overall more bends, a bending die can perform the job of bending behalf of the welding an joining hence reducing man-hours and production costs. Welding: The material which is used LOW CARBON STEEL has good weld ability. All welds on the vehicle are made using a MIG (metal inert gas) welding process.MIG welding uses an arc of electricity to create a short-circuit between a continuously fed anode (+ the wire fed gun) and a cathode (-the metal being weld). MIG is selected because it provided the best control of heat affected zones while also reducing internal stress in the frame selected it order to allow the weld to flex slightly without cracking. It provides strongest welds, faster welding speed and is clean and efficient makes welding easier. LOW CARBON STEEL is one of the most common of all metals and one of the least expensive steels used. It is very durable.

Having less than 2% carbon it will magnetize well. Being a softer metal it is easily welded. This is in contrast to other high carbon steels lie stainless steel which require specialized welding techniques. Less brittle and can therefore give and flex in its harder more application simply crack and break. Engine and Specifications

Wheels, in connection with axles, allow heavy objects to be moved

easily facilitating movement or transportation while supporting a load. The selection of tires according to the requirements of performance, event, as well as budget plays an important role.

We are using wheels of size: Front: 10 x 4.5 x 5 (Tyre dia x width x rim) Rear: 11 x 7.1x 5 (Tyre dia x width x rim)

The objective of selecting this tyre is to get required ground clearance. It is very important that the kart runs at low levels of sound and is also low on pollutants; hence a muffler with a high fuel exhaust is provided which not only reduces the noise and vibrations, but also reduces the pollution and increases the engine performanceple of a figure caption. STEERING SYSTEM DESIGN: Objective: The steering system is designed to withstand the stress of safely maneuvering the vehicle through any type of possible condition at the time of driving. The purpose of steering system is to provide directional control of the vehicle with minimum input.

The main goal for steering is to have steering radius of 4m or less and to have 100% Ackerman steering.

Design: Simplicity and safety were the main design specifications for the vehicles steering system. While designing the steering system the constraints that we possessed were center alignment of steering system, track width, human effort at the steering wheel and the desire the response of the steering system. A Pivot Pin steering arrangement was chosen due to its light weight, simple design and low cost. Very less splay due to limited number of joints.We are also introduced the multi sensitive steering system. This system has a tendency to increase or decrease the sensitivity of our steering by means of multi-port pivot plate, by changing the position of tie rod from port one by one. This system provides the driver simplicity and directional control over vehicle according to condition. The formulae used for steering calculations are: cot ϕ-cot θ=c/b R= (b/ sin ϕ)+((a-c)/2)

MECHERA

Page 10

Where, R is the turning radius, b is the length of the car, θ is the angle of inside angle of the wheel, ϕ is the angle of outside wheel, c is the distance between the pivot points To determine the Ackerman percentage, equation (2) is used,

Given that, 100% Ackerman angle is desired. A at 30 and B at 22 was the best option. This gave a turning radius of 3.2m. In geometry when a car taking a relative wide turn, the point where axel lines intersect is the point about which the car is turning. Our tires is not skidding because the inside front wheel is angled just a little more than the outside front wheel .inner and outer turning the angle is calculated by the formulae- Outer angle- Tan A=L/(R-d/2) Inside angle – Tan B=L/(R+d/2) Caster angle is the most important factor governing how the kart will handle. It will make the kart more stable in rough condition and the karts straight line stability will also be improved. Kingpin inclination is used to making a steering tend to return to the straight ahead or center position. If kingpin is incline at 7degree, it gives self-centering effect and leads to less steering effort.

BRAKE SYSTEM

� OBJECTIVE:

The purpose of the brakes is to stop the car safely and effectively. In

order to achieve maximum performance from the braking system, the brakes have been designed to lock up rear wheels, while minimizing the cost and weight.

� DESCRIPTION: �

The brake system design includes the double disc at the rear axle to stop the vehicle. It is mounted in the 7inch far from the wheels position of the axle with opposing the position of drive train sprocket hence also enables the good requirement.

Master cylinder is used at the front near the brake pedal providing the occupant to easily accessible space. Proper master cylinder bore size was found by doing brake calculations based on the mass, center of gravity, master cylinder volume size and various dimensions of the vehicle. Though braking power increased with a decrease in bore size, the volume of brake fluid that was able to be displaced decreased with decreasing bore size. FRAME FINITE ELEMENT SAFETY ANALYSIS: -

Theoretical calculated loads were placed on a wireframe model of the frame at critical points to simulate the amount of force that vehicle would undergo from its own weight and the driver in the event of collision. Analysis was conducted using FINITE ELEMENT ANALSIS (FEA) on AUTODESK FUSION 360 software. To conduct the finite element analysis of the chassis an existing design of the chassis was uploaded from the computer, stresses are calculated by simulating two different induced load cases. The value of the force in different cases of impacts is calculated by the procedure as follows- FRONT IMPACT ANALYSIS: -

Generally, in the case of pure elastic in frontal impact the linear velocity remains 40 kmph. Hence the value of force is calculated by mass moment equation that is:- F= P x ∆T Where ∆T is the duration of the collision takes place for every short duration of time. We assumed the time as ∆T= 1.1 seconds. And the gross weight of the vehicle is estimated around some (M= 200 kg), Hence the moment of the vehicle at 40 kmph or 11.2 m/s that is :- P= M x V P= 200 x 11.2 P=1344kgm/s And the frontal impact force i.e, F= P x ∆T

MECHERA

Page 12

F= 1344 x 1.1 F= 1478 N F≈ 1500 N

Now the calculated force were placed on the frontal part of the frame by keeping the part fixed on the AUTODESK FUSION 360 the result along with the image is as shown

SIDE IMPACT ANALYSIS:

Similarly, calculated value of the side impact force was placed on the side part of the frame while keeping the frontal part fixed. The analysis result is as shown,

Hence the conclusion of the safety analysis with the result is tabulated.

DESIGN STRESS / YIELD STRESS

With the data collected from the FEA simulations, the roll cage was found to have a theoretical factor of safety of approximately more than 2.0. This result also illustrate that the frame ensure the maximum amount of driver safety resistant. Attaching the seat belts to the most rigid and structural chassis components guarantees reliability of the seat belt under the extreme forces possible in a collision. Using a quick release lever style seat belt clasp gives the driver the ability to get out of the vehicle in a safe amount of time in the safety restraints provided in the car will be sufficient for keeping a driver in the event of collision, while still allowing the driver to escape in the required amount of time.
