摘　　要：分析了汽车发动机罩板的拉延成形特性,通过运用UG进行工艺补充面设计,同时给出了利用软件Autoform对零件拉延成形进行有限元分析的步骤。基于CAE分析结果,探讨其中出现的缺陷(如起皱、破裂、变形不足等)的原因,提出解决方案并再次进行仿真,最终得到合理的拉延成形方案。The drawing and forming characteristics of automobile hood are analyzed. The addendum surface is designed using UG, at the same time, the steps of finite element analysis for parts drawing and forming by Autoform are given. Based on the CAE analysis result, the reason of defects （such as wrinkling, rupture, deformation problems） is discussed, a solution is proposed and simulated again, finally a reasonable drawing process is achieved.
