A-Arm Buckling end conditions?
A-Arm Buckling end conditions?
(OP)
Hi I was wondering what the proper Euler Buckling end conditions would be for a individual tubular a-arm link would be. The links are welded to a steel boss with a spherical bearing. The other end of the link has a threaded rod end attached to it. I am thinking that you can assume that the end with the rod end is a pinned joint (no moment support) and the end at the ball joint is fixed. Therefore the effective length would be .7L. Or would a model with both ends fixed be more accurate (ie. effective length of .5L)?
Thank You
Thank You

Shouldn't really matter unless you have an extraordinary design, I've worked on very few suspension parts where buckling was a big design issue (two, from memory, neither were A arms).

Given that arms do occasionally get bent it pays to be ultracautious.
