摘　　要：利用板料成形模拟软件Dynaform对某轿车非典型U形件的冲压成形过程进行模拟,研究凸、凹模间隙、凸模速度、摩擦因数等对板料成形后厚度的影响,经多次模拟及对模拟结果进行分析,确定可行的成形工艺参数,用于指导实际生产。Dynaform, the sheet metal forming simulation software, was used to simulate the stamping forming process of an atypical U-shaped part of a car. The impact of the punch and die clearance, virtual punch velocity, friction coefficient and other factors on the form- ing sheet thickness were studied. After several times of simulation and analysis, the reason- able forming parameters were achieved for the practical production.
