摘　　要：用有限元模拟矩形盒拉深成形过程并剖析拉深中材料流动变形规律。选用更接近拉深过程本质的动力显式算法和效率更高的壳单元来模拟非回转对称体的成形过程。实验验证了矩形盒成形有限元模拟结果的可靠性。The forming process of rectang ular case drawing is simulated and the rule of material flowing deformation in the process of drawing is analysed.When forming process of non-rotative symmetrical object is simulated,dynamic explicit arithmetic according more with the practical condition and shell element with higher efficiency are selected.The reliability of results of rectangular case forming FEM simulation is validated by experiments.
