摘要
采用动态显式有限元方法和目前在板料有限元数值模拟中最常用的Hill各向异性屈服准则对筒形件拉深过程的变形情况进行了分析,得到各种不同的工艺参数对板料成形性能的影响,从数值模拟方面预测各参数对简单筒形件拉深中的变形影响。
With the dynamic explicit finite element method and the Hill's anisotropic yield criterion,which is widely used in the current finite element analysis,the influence of various kinds of process parameters on the forming property of cup-drawing is analysized, and the developing trend is also predicted through the numerical simulation.
