摘　　要：在对所研究材料双相钢DP600的力学性能测试基础上,完成双相钢的非回转对称性拉深的有限元模拟,对非回转对称性盒3条特征曲线上的厚度分布、应力应变状态三方面进行分析。详细解释断裂点的产生原因及断裂本质,可为预测类似形状零件的拉深缺陷进而提高成形极限提供一定的参考。Based on the study of the materiars mechanical properties of dual phase steel DP600, this paper completes finite element simulation of non-rotating symmetry drawing with dual phase steel. It analyzes the thickness distribution and the stress -strain state on the characteristic curve of non-rotational symmetry box. It also explains the causes and fracture nature of the breaking point in detail. It is able to predict drawing defects of part with the similar shape and then improve the forming limit for some reference.
