Occupant Packaging Workspace Anthropometry :

Conventional Static Measurements

anthropologist(are taken on the human body in rigid ,

standarized position)

Functional Task Oriented Measurements

Engineer Designer

(are taken with the human body at work ,in motion or in workspace attitude andtypically are expressed as 3dimensions.)

Driver workspace design and evaluation models

Task Oriented Percentile Models

- Use anthropometric data to Define a userpopulation startified across stature , weightand

- Conduct test for specific task(reach, eyelocation) to develop statistical modelsdefining spatial requirements

- Assume that sample populations defineduser requirements- assumes user needs are

expressed by a centraltendencywith exclusionat both ends , for example95 percent accommodation with 2.5percent excluded at each end.

- many level of accommodation aredescribed , but only for the task studied

- Results in well defined statistical modelthat defines accommodation levels forspecific task

Manikin Oriented Models

- Uses anthropometric data to define 95

percent male and 5 percent female- uses manikins or selected large (95%) male

and small (5%) female to define spatialrequirements

- Assume that Specified large males and smallfemale comprehend all user requirements

- Assume that 2-D (or 3-D) manikins canpredict or model human requirements- Assume that a given percentile person is

definable from the some of parts- Many task are measured and evaluated , but

only for a defined small and large user- Result in questionably defined geometric

manikin models that predictaccommodation for only two extremepercentile people

Engineers will simulate driver behavior and measure key criteria such as reach,visibility, comfort, posture, biomechanics, strength and anthropometrics. This analysis willenable the team to make driver-oriented decisions about cockpit design, while respectingthe overall aerodynamics of the racecar body.

The SAMMIE System

The SAMMIE system is a computer based HumanModeling tool. Its capabilities make it an invaluabletool to designers and design teams working onproducts that are used by people.

The system offers the following advantages:

3D analysis of fit, reach, vision and posture.reduced timescale.early input of ergonomics expertise.rapid interactive design.improved communication.cost effective ergonomics

Automotive Seat Design For Sitting Comfort

Criteria for a driver s seat :

1: the set should position the driver with unobstructed vision and within reach of allvehicle control

2: the seat must accommodate the driver s size and shape

3: the seat should be comfortable for extended period

4: the seat should provide a safe zone for the driver in a crash

Safety Tips In Crash

Safety in a race car is the art of protecting thehuman occupant, at whatever cost to the car.Designing the car to be damaged minimallywhile hindering driver safety is definitely thewrong approach.

The diagram shows that pretty much any partof the body exposed to the chassis of the racecar is at risk. Injuries occur because the bodysustains impacts beyond the G (gravities) level

that it can sustain.

Use energy absorbing materials in thecollapsable crash structure

For light weight, use a stressed skin over

a lightweight core material - Triangulate the driver "safety cell" toprevent collapse

Use a clear windscreen or bodywork toincrease vision

Keep the fuel cell and battery away fromthe driver and danger.

Don't scrimp on safety.8

Design Of Symbols ForAutomobile Control and Displays

1) Digital metersDiscreet digital meters maximize forwardvisibility and help create a sense of uncluttered spaciousness.

2) Triangle-motif steering wheelThe triangle-motif steering wheel helpsharmonize exterior and interior design, fora feeling of unity throughout.

3) Centrally positioned audio panelA 2DIN opening for audio components iscentrally positioned at the top of theinstrument panel for easy access andvisibility.

4) Textured dashboard and console

The dashboard centre, floor console, andfront pillars are trimmed with a newtextured material with a refined look andfeel.

5) Sporty two-tone fasciaThe sporty two-tone fascia adds a touch of pizzazz to the Liana's interior.
