摘要：

汽车轮辐零件的制作是一个多工步冲压成形过程，在最后一道工序圆孔翻边时经常出现开裂。利用仿真软件对汽车轮辐零件的成形过程进行有限元模拟分析，讨论了圆孔翻边系数、材料参数和成形工艺对翻边成形的影响。结果表明，材料屈服强度的增加对翻边开裂有很大影响。通过改进翻边工艺，使轮辐零件圆孔翻边开裂缺陷得到控制，开裂率降低到0.1‰，获得了较好的产品质量。

Manufacturing the automobile spoke components is a multi-step stamping forming process, the round-hole flanging often cracks in the last process. The forming process of automobile spoke component was analyzed by finite element simulation software, and the influences of the round-hole flange coefficient, material parameter and forming craft on flange forming were discussed. The results show that the increasing of material yield strength has a great influence on the flange cracking. Through improving the flanging process, the cracking defects of the round- hole flanging in the spoke components were controlled, the cracking rate reduced to 0.1 ‰, and better product quality was obtained.
