Hi all, this is my first post on Physics forums so I apologise in advance if I have posted in the wrong section etc. This is something that I have been trying to figure out for nearly a week now! I have modeled a vehicle in Solidworks, specifically an external roll cage, and hope to conduct a stress analysis for the vehicle rolling over. What I am trying to obtain is a suitable force to apply to the edges of the roof corners that make contact with the ground. After fumbling through more equations than I have space for on here and utterly confusing myself reading books on vehicle crash mechanics, I have reached the conclusion that I need help!
Some information I can give;
Vehicle turning circle = 11.58m,
Track width = 1.308m,
Total width = 1.628m,
Vehicle height = 1.969m,
Center of gravity height = 0.665m,
Curb weight = 1315kg,
If there is anymore information needed I will do my best to provide it.
I know for this subject there is a multitude of different variables, for this particular application however I am looking for the highest value of force to obtain a 'worst case' scenario. For simplicity I have been assuming the vehicle to be a solid model, taking the compression of suspension as negligible. I can appreciate that this post is vague at best, but I would certainly appreciate any help out of this mess that I am in.
Thanks, Louis.
