摘　　要：结合逆向工程技术和数值仿真模拟技术,在汽车覆盖件模具创新设计中提出了新的看法,通过一个覆盖件的实例具体介绍了在逆向CAD建模和有限元建模过程中的关键技术和实践技巧,应用Dynaform软件进行具体的CAE分析计算,解决了分析过程中的砂漏问题,得到与实际相符合的结果。The reverse engineering （ RE ） and numerical simulation technology were applied in the design of automotive panel die. Some new points of view in innovating design of the automotive panel die were presented. Some key technologies and exercise skills in the CAD and FE modeling processes were introduced by an example of automotive panel, the calculation and analysis was made by using Dynaform software, and the problem of hourglass was solved in the analysis progress and the obtained result accords with the fact.
