  • This clevis is used at different nodes, similar to the bearing housing cap

    • Front and Rear UCA

    • Front and Rear LCA

  • The greatest resultant force (Fr) at any of those nodes will be used to test that case

    • Fr = sqrt(Fx^2 + Fy^2), angle = atan2(Fx,Fy)

  • The force is applied on the inner portion of the clevis on the face corresponding to the direction of that force

Recommendations

Improvements can be made to the sim, i think i should have a virtual wall fixture where the bolt head would be, that would probably improve the accuracy. Anytime a stress goes over 10^8 in the sim i dont really trust it. The virtual wall on the back of the part isnt really doing anything except in the special cases.

I also guessed the size of the Fz contact area, but will redo once i have confirmation or a better estimate. -MPClevis passes all sim cases well under the yield strength of the part, so there is room to remove material if needed.
