Finite element simulation of PM gear rolling process

Abstract

The programme for the powder metallurgy (PM) gear rolling process to predict the densification and deformation behaviours was developed through the finite element method. The compression test was carried out to obtain the material parameters for Shima-Oyane model including six parameters with respect to yield surface and workhardening. Those parameters were employed to analyse the densification behaviour of porous material during the rolling process. The simulation results with respect to the plastic deformation and the densification behaviour of the PM gear were confirmed and verified with the experimental results.
