1. Nut, washer and locking device removed from model

2. This free face was causing meshing failures; was removed from FEM

3. Solid body mesh mating conditions applied to both sets of rod end and rod body.

4. CRES bearing insert and housing were united as uniform material for both rod ends 3D tetrahedral mesh elements applied with.200” element size. Rod end FEM properties – AISI4340 CRES Rod body FEM properties – AA2024 T3 Mesh mating conditions aligned correctly at nodes between the two different solids Rigid body element wagon wheel with infinite stiffness tied between centerpoint and bearing i.d. at both rod ends

5. 5000 lb load direction downward at upper rod end centerpoint Fixed single point constraint at lower rod end centerpoint

6. Mode 1 Eigenvalue =.56 Max Run Time = 10 MIN
