We are designing a FSAE and I have to design the suspension elements. All dynamic calculus are finished, but I have to design uprights, wishbones, pushrods…
My question is about ball joints how can I calculate the size I need.
I think I must take the loads at the contact patch and translate them to the joints, but if I do that the forces at joints are very high. I’m thinking that it could be because my loads at the contact patch aren’t right.
My critical loads for a 290kg car are:
Longitudinal Load: 1.400N
Lateral load: 960 N
Vertical load: 1.200 N
Are too high?
Please say me if the “my process “ is wrong.
