摘　　要：采用有限元软件MSC Marc基于拉格朗日的弹塑性本构方程 ,对减振钢板的拉深变形进行了数值模拟。模拟中特别考虑了接触边界条件和材料特性。得出了变形过程中的应力应变状态和错动量分布 ,以及影响错动量的因素。为减振钢板的成形工艺设计提供了理论基础。A numerical simulation of the drawing process of vibration damping steel sheet(VDSS) is investigated by FE software, MSC.Marc. The description of contact boundary condition and material property is specially considered. The underlying formulation is based on Lagrangian elastoplastic materials model. Cauchy stress, plastic strain and slipping-off distribution in the workpiece during drawing process are given and the factors which influence the slipping-off are considered. Therefore the theoretical foundation can be provided for the design of forming process of VDSS.
