摘　　要：基于连续介质力学及有限元理论,运用动力显式算法建立有限元模型,采用ANSYS/LS-DYNA软件模拟圆形板料的拉深过程,在三种不同加载路径下,研究圆形板料在拉深方向的最大应力和板料厚度的变化规律,以及不同加载方式对板料成形质量的影响,所得结果可为生产实际提供指导。Based on the continuum mechanics and finite clement theory. A finite element model has been established by using the dynamic explicit algorithm, and the stamping process has been simulated by using ANSYS/LS-DYNA program. With three varied loading routes, variational rule of maximal stress in the direction of deep drawing and thickness of the round sheet-metal blank have been studied, and influence of forming quality has been analyzed. Results obtained can be a guidance of production.
