摘　　要：在CAE技术的基础上,通过正交试验研究了车用侧墙板冲压成形过程中压边力、摩擦条件、拉深筋、模具间隙4种主要的工艺参数对零件成形质量的影响,通过统计技术对零件成形性能数据(最大减薄率和变形不充分性)进行了极差分析,在正交试验结果的基础上分别对最大减薄率和变形不充分率进行工艺参数优化。研究结果表明,4种工艺参数中压边力对侧墙板零件减薄率和变形不充分性的影响最为显著,由正交试验得到的优化方案能有效地减小最大减薄率和变形不充分性。Based on CAE, the effects of stamping process parameters （blank holder force, coefficient of friction, height of draw bead and die clearance） on the formability of an automotive sidewall plate were investigated by orthogonal experiment. The maximum thickness reduction and deformation insufficiency of the sidewall plate were examined by range analysis. And then the process parameters were optimized for the maximum thickness reduction and deformation insufficiency respectively. The results show that the blank holder force affects obviously the formability of the sidewall plate. The optimization of the process parameters obtained hy the orthogonal experiment results can effectively reduce the max. thickness reduction and deformation insufficiency.
