摘　　要：使用美国ETA公司的CAE软件Dynaform,通过求解器LS-Dyna计算,利用ETA/Post-processor来模拟某轿车引擎盖内板的拉深成形。通过模拟结果的比较,最终确定拉延筋的最佳布置方案及拉延筋的优化形式等。缩短了模具设计周期,降低了设计成本,提高车身质量。By using increment simulation software ETA/Dynaform, the forming process of a car engine inner panal was calculated by LS-Dyna and simulated by ETA/Post-processor. The optimal setting and shape of drawbead were determined by comparing the simulation results. The improved design could shorten the development cycle of die, reduce design cost and improve the quality of car body.
