摘　　要：采用有限元分析软件DYNAFORM,模拟了08Al钢板的杯突成形过程,并结合杯突试验研究了该过程平均摩擦系数。结果表明,模拟与试验结果基本吻合,杯突值与平均摩擦系数之间存在显著的线性相关性,且由此得到的回归方程式可用于杯突试验以测定该成形过程平均摩擦系数。By means of FEM analysis software DYNAFORM,the processes of cupping 08A1 steel sheet have been simulated and their mean friction coefficients researched compared with cupping tests, resulting in that the simulated results were similar to the test one and there existed a remarkable linear relationship between the mean friction coefficients and the cupping values （EI）,by which a regression equation has been obtained for cupping test to measure its mean friction coefficient.
