Crash test

Altair Forum User

Hello sir,

I am having a problem in a dynamic crash test of the vehicle.What happens is that the vehicle used to come back after hitting the wall but I want the simulation to end once after hitting the wall.Also, Is it possible to make a dynamic crash test or head on collision of two identical vehicle in radioss?If yes,how?

Hi Ayush,

Please check the modelling parameters, that is material parameters, contacts defined, boundary and loading conditions...etc. Any irrelevant information in these parameters can result in like a 'bounce-back'effect. I recommend you to go through RD-3550: Simplified Car Front Pole Impact tutorial in the Help Menu  which will give you a fair idea on car impact analysis.

You can perform head to head collision of vehicles in RADIOSS. The user should apply the required loading conditions in both the cars.
