摘　　要：针对钣金件冲压成形后会出现起皱、拉裂等各种缺陷问题,基于Dynaform软件,以汽车纵梁为研究对象对其进行冲压成形仿真。结果表明,通过设置拉延筋的方式来控制各部位材料流动的速度能显著改善零件的成形质量。Aiming at wrinkling and cracking in stamping process,the stamping process of auto carling was simulated based on Dynaform software.The results show that using the drawbead to control the flow velocity of metal material can improve the forming quality of the parts.

关 键 词：冲压数值模拟 DYNAFORM 拉延筋
