Abstract：

Friction plays an important role in plastic volume forming.It is a key question for friction model and friction coefficient between rough material and die in finite element simulation of plastic volume forming.It was studied by ring compression method.Sets of friction coefficient calibration curves were obtained by finite element analysis for ring compression.A curve between inner diameter and ring height was determined by sets of ring compression tests under some lubricating conditions.Friction coefficient was obtained by contrast curve from ring compression tests to sets of friction coefficient calibration curves.The friction coefficient between 6A02CZ and steel in plastic volume forming was determined as a sample.The friction coefficients were 0.325 and 0.3 respectively under free lubricant and lubricating oil.It is better for finite element analysis of plastic volume forming.
