摘要：

基于Dynaform有限元模拟软件，对汽车离合器传动带零件冲压成形中的工艺参数进行优化，结合正交试验分析了模具间隙、冲压速度和弯曲角度与传动带零件成形高度之间的变化关系。分析结果表明，影响传动带零件成形高度的顺序依次为：模具间隙＞弯曲角度＞冲压速度；确定了传动带零件冲压成形的优化工艺参数为：模具间隙为1.1t，冲压速度为2000 mm·s-1，弯曲角度为165°。此外，对优化后的试验方案进行有限元模拟，得出传动带冲压成形零件高度的模拟值为5.04 mm，并对其进行冲压成形实验验证，得到传动带零件高度的实验值为4.73 mm，与模拟高度值相比误差为6.15%，从而证明了优化后的工艺参数可以较好地指导离合器传动带的冲压模具设计。

Dynaform was used to optimize the process parameters in the forming of clutch strap, the influences of die clearance, stamping speed and bending angle on forming height were investigated by orthogonal experiment, the results show that the sequence of influencing factors on forming height of strap is die clearance, bending angle and stamping speed respectively. In addition, based on the analysis of orthogonal experiment for the forming of clutch strap, the optimized stamping process parameters are obtained with die clearance 1.1t, stamping speed 2000 mm·s-1 and bending angle 165°, In addition, the value of simulation for forming height at optimized experiment is 5.04 mm, Furthermore, the calculated result is verified by the experimental result with 4.73 mm, the error between calculated result and experiment result is 6.15%. Therefore, the process parameters after optimization can guide the die design of clutch strap better.
