数值模拟在汽车覆盖件成形中的应用

APPLICATION OF NUMERICAL SIMULATION IN CAR PANEL FORMING

有限元分析方法已被广泛应用于力学过程的计算机仿真，对冲压生产等工程问题的应用也逐渐得到人们的重视与认可。本文应用法国ＥＳＩ－ＧＲＯＵＰ的大型有限元软件ＰＡＭ－ＳＴＡＭＰＴＭ进行了汽车覆盖件成形仿真，并与实际生产结果进行了对比分析，以此介绍数值模拟在汽车覆盖件成形过程中的应用。

FEM simulation has been widely used in the field of dynamic analyses,and it is also accepted in production environment,like stamping By comparing the prediction of PAM STAMP and experiments,this paper introduces the application of numerical simulation for car panel stretch draw process
