Paper Title:
Research on Stress and Strain Distribution during Multi-Pass Conventional Spinning under Different Roller Motion Modes
  Abstract

Establishing a reasonable mechanical model for multi-pass conventional spinning and typical drawing spinning is the object of the present study. Research on stress and strain distribution during multi-pass conventional spinning processing under three modes of roller motion, i.e., one-way moving without profiling, one-way moving with profiling, and two-way moving with profiling, is carried out using elasto-plastic FEM method. Though the equivalent stress distribution under these three modes of roller motion is similar, there exists significant difference in magnitude, with the equivalent stress in the close-mandrel area being the highest in the case of profiled one-way moving. As far as the strain is concerned, it has a similar distribution as the equivalent stress, with the strain in the close-mandrel area under one-way moving with profiling having the highest value. In the case of roller two-way moving with profiling, the strain distribution is the most homogeneous, while the work-hardening of the blank is the most serious. In all cases, both stress and strain in the deforming zone increase with increasing spinning passes.
