Numerical simulation and analysis of residual stress field at the lower end of shot peening steel ring

Abstract

In this paper, an X-ray diffractometer is used to determine the residual stress of the lower end of the steel ring at the joint surface of the rim lock ring groove. Analyze the distribution of residual stress on the lower end surface of the steel ring before and after shot peening, and perform a finite element model simulation analysis on the lower end of the steel ring based on abaqus/fem-dem coupling, and realize the finite element simulation of a large number of projectiles impacting the target. The simulation results are verified. It provides a new method for the coupling finite element analysis of a large number of projectiles and structures for shot peening.
