Hey hi guys,
Currently I am working on the analysis of uprights and hubs .I have some doubts related to constraints to be applied on model.I am doing this analysis in ansys 13 workbench.
For knuckle I have totally fixed the points connected to wish bones and tie rod and applied forces and moments on the knuckle centre and for hubs, I have applied cylindrical constraint at centre of hub (part between brake disc and wheel) keeping its tangential movement free and have fixed its motion in lateral direction.I would also like to know method to perform fatigue analysis in ansys. I tried finding it on internet and tutorials but could not get any clue.Your suggestions on them would be valuable for me.
I have some more doubts related to suspension.We are trying to find out K value for our springs.But we don't know what would be the best estimate for stiffness of tyre.Right now we have assumed it to be 212384 N/m.And I would also like to know the best software for doing kinematic and dynamic analysis of car ,We are using adams car but I am not able to get FSAE database for that. I downloaded it from their official website but its not really helping. Whether using ARB would be good idea for first year team or not???. We are trying to keep our a arms trailing in rear( not trailing arm geometry).Will it cause any problems???
Thank you, hope you will reply
