摘　　要：为了改善某汽车前副加强板冲压成形中的起皱、开裂和回弹现象,采用有限元软件Dynaform结合正交试验和极差分析获得各评价目标的工艺参数,通过多目标优化软件Design-expert获得零件最优工艺参数,采用节点补偿法获得回弹补偿模型,并对最优工艺参数和回弹补偿模型进行仿真分析。结果表明:最优工艺参数的仿真和回弹补偿效果较好,零件的成形极限状态良好,最小厚度、最大厚度和最大回弹量均符合设计要求。In order to improve the wrinkling,cracking and springback phenomena in the stamping forming of the front vice reinforcement plate of an automobile,the finite element software Dynaform is used to obtain the process parameters for each evaluation target by combining orthogonal tests and extreme difference analysis.Through the multi-objective optimization software Design-expert,the optimum process parameters for the components are ob-tained.The node compensation method is used to obtain the rebound compensation model surface,and the opti-mal process parameters and rebound compensation model are simulated and analyzed.The results show that the optimum process parameters and the effect of springback compensation are good,the forming limit state of the parts is good,and the minimum thickness,maximum thickness and maximum springback meet the design re-quirements.
