摘要
在解决大型复杂形状冲压件，尤其是汽车覆盖件的冲压生产技术问题时，圆网格方法已卓有成效。但对成形量小的浅拉延件，传统的圆网格法已不能满足要求。本文以ＣＡ１４２汽车后轮罩为对象，利用一种新的网格方法，计算了应变、应力等高线，分析了后轮罩出现冲压缺陷的原因。
Circular grid method appears effective in solving technological problems of large stamping components with complex shape especially of automotive panel. Nevertheless, traditional circular grid method is no longer applicable for shallow stretching components with small forming capacity. In this paper, a new griding method is introduced to calculate strain and stress contour for rear wheel cover of CA142 truck and the reasons for stamping defects are analyzed.
