Numerical simulation of the plunge stage of friction surfacing of AA5083 aluminum alloy

Abstract

Plunge stage is crucial to the success of whole friction surfacing process. To investigate the effect of parameters, the CEL modelling method in the finite element software model was used to simulate the plunge stage of friction surfacing. The results showed that the higher rotation speed would result a smaller axial force but higher the center point temperature and frictional dissipation; Besides, a higher feed rate, who can cause higher peek value of axial force and the center point temperature rises faster, is inversely proportional to the frictional dissipation, and the final axial force and the center point temperature tended to be in the same range.
