Nut, washer and locking device removed from model
This free face was
causing meshing
failures; was removed
from FEM
Solid body mesh mating conditions applied to both
sets of rod end and rod body.
• 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
Rigid body element wagon
wheel with infinite stiffness
tied between centerpoint and
bearing i.d. at both rod ends
Mesh mating conditions
aligned correctly at nodes
between the two different
solids
5000 lb load direction downward
at upper rod end centerpoint
Fixed single point constraint at lower
rod end centerpoint
Mode 1 Eigenvalue = .56
Max Run Time = 10 MIN
