摘　　要：借助Auto Form软件,利用汽车板成形的有限元模拟分析技术,对某车型后纵梁冲压设计工艺方案进行了模拟分析。为了消除U形纵梁成形缺陷,进行了正交试验设计,根据CAE技术在模具设计调试过程中的指导作用,并依据模拟结果对零件拉延工艺方案进行分析、判断和优化,通过对拉延筋参数进行优化,解决了后纵梁回弹问题。With AutoForm software, the use of automobile sheet metal forming finite element analysis techniques for the design of a vehicle rear side stamping process plan simulation analysis. In order to eliminate the U-shaped stringers forming defects, the orthogonal experimental design, die design based on CAE technology in the guiding role of the debugging process, and based on the simulation results on the part drawing process solutions for analysis, judgment and optimization, by drawing tendons parameters are optimized to solve the rear side springback.
