We found multiple post on this topic but haven't found the answer to our problem.
We have the geometry for the chassis, suspension points etc etc etc.
We done the calculus of the moment of inertia (Pilot, Engine Frame and Wheel uprights, brake, A-Arms assembly, were using the info of the torque of engine) basically that are all the loads were going to consider at this time.
We know were and how to put this loads in different condition: Brake, Acceleration and Curve handling.
Our big problem is were to constraint the frame for our FEA.
I think in putting them in all the suspension joints with the chassis
My partner thinks that the constraints are different for every case,
and we are even thinking of not using any restraint so we can see how it all deforms!!!
So as you can see were in a bit of a problem!!!
This is are first time doing the FEA in the Frame, we have some FEA experience very simple so we know how to interpret the numbers.
If you could tell us how you constraint your frame we would really apritiatesd!!!
Thanks
