摘　　要：随着我国的汽车工业不断发展,各车企之间的竞争也在不断加剧,在新车型的开发过程中,车身外覆盖件外观质量和尺寸精度要求越来越高,从而给汽车模具生产行业也提出更高的要求,汽车外覆盖件在冲压成形时会产生各种类型的缺陷,其中回弹仍是汽车冲压行业的一个挑战。通过一个成功的前车门外板案例,借助Autoform软件阐述一种汽车外覆盖件全工序回弹分析和补偿的应用。全工序模拟完全按照模具实际生产现场的边界条件进行模拟,同时通过稳健性分析以确认各因子的影响,最终保证回弹补偿的准确性,可为汽车外覆盖件回弹补偿提供参考。With the continuous development of the automobile industry in China,the competition between automobile companies is also increasing.In the process of developing new automobile,the quality and size accuracy of automobile panel are increasingly high.Thus to the die production industry also put forward higher requirements,the panel will produce various types of defects during stamping,springback is a challenge for the automobile stamping industry.Through a successful study of the front door outer panel,this paper expound the application of automobile panel process springback simulation and compensation with Autoform software.The full cycle simulation is done according to the boundary conditions of the actual production site of the die.At the same time,the influence of each affecting factor is confirmed by the sigma simulation,and the accuracy of the springback compensation is finally guaranteed,which can provide reference for the springback compensation of the other automobile parts.
