Design of Car Chassis

[waqaskhan200]

Hi,
Well i have a project of designig a car chassis ad i really needed help on the different forces that act on the chassis during operation and their position on the chassis.
If anybody could help me please.

It would be helpful if you can elaborate upon what sort of application is involved.

[brendank]

Forces acting on the chassis would simple be forces from the suspension and shock absorber points and forces translated through the the axles. To figure out what those are depends on the application and configure of the components. Chassis design depends completely on suspension design and drive train components and configuration.

And, I would imagine, also the aerodynamic forces. :wink:

Also some rather large transient loads, if you crash the car :smile:

[brewnog]

Torsion from the road surface, torque from drivetrain and brakes, weight of supported components, reactions at suspension and steering mounts, inertial forces....

... use your imagination.

[lokesh84]

to start with just look after your specification for vehicle and decide the points of load application for suspension and body anolg with the axles.
once you are through with it go for stage wise calculation
A. static
which involvs just weight of the various loaded components and parts
B. dynamic
which involves forces due to road bumps through shock absorbers , engine torque actin as inertial forces, aerodynamic forces by air density and area of car encountered by it. but remember take into account forces in lateral, longitudnal as well as transverse direction

proper torque is very important to ensure no loose nut behind the steering wheel

Hopefully the OP finished his project since it was started 2 1/2 years ago and he never replied since then.
