摘　　要：采用作者设计的一种新型测量薄板深冲成形过程中工具与工件之间摩擦系数的模拟装置 ,测定了相同材质的带材在不同条件下的摩擦系数。测试过程中改变润滑条件、辊距及带材的表面取向 ,测试结果表明摩擦系数与润滑和冲头的几何形状有很大关系。为计算机有限元模拟提供真实摩擦边界条件 。All friction coefficients between deformed press and die during sheet metal deep drawing were tested using new kinds of friction test device designed by authors.The sameness materials friction coefficients were measured with different lubrication condition,Punch form and surface state.The results show that the friction coefficients of sheets are extremely influenced by lubrication and Punch form.FEM simulation of computer truly friction bound condition were provided.It is lay foundation that the results reliability of finite element method(FEM).
