Abstract


Based on the cover of the motor vehicles often surface depression and distortion generation features, design one set contains four anti- stamping test mold drawing shapes , regularity and mechanism used to analyze the surface depression and distortion . Order to monitor surface defects generated in the \By pressing the test , in the Class \Through the analysis of the test results and numerical simulation results , anti - drawing the shape of three feature size variable surface depression and distortion of stamping specimen stress in the Class \distribution and tendency to study the mechanism of the surface depression and distortion .
