Abstract:
A multistage warm/hot forming is simulated for the cross grove
outer race of constant velocity joint, using a thermo-mechanical
coupled rigid viscoplastic finite element method, and specially
some problem for process development and die design are
analyzed. A forming test shows that computed results have good
agreement with experimental results. Above obtained results can
be applied to development of multistage warm/hot forming process
and die design for outer race.
