摘　　要：通过介绍机械摩擦理论的发展历程、研究成果及其不足之处,分析了冲压摩擦的形成机理,并从摩擦副特性、冲压工艺参数、界面接触状态3个方面总结了其影响因素以及摩擦模型的研究现状。研究发现,冲压成形中摩擦形成过程十分复杂,涉及的非线性影响因素很多,而现有的摩擦机理由于忽略了一些重要因素,如温度、弹塑性形变、模具磨损等,不能充分反映其形成过程。而且,在构建摩擦模型时,各因素之间的关联性也未被充分考虑,由此建立的摩擦模型精度不高。因此,全面综合地考虑宏微观因素对冲压摩擦的演化过程及其形成机理的影响,建立一种多因素耦合的动态摩擦模型,这也是未来研究板料冲压成形中摩擦形成机理的一个重要方向。The development process,research results and shortcomings of mechanical friction theory were introduced,and the formation mechanism of friction in stamping was analyzed. Then,the research status of its influencing factors and friction model were summarized from three aspects of the characteristics of friction pairs,the stamping process parameters and the interfacial contact states. The results show that the formation process of friction in stamping is very complicated,and there are many nonlinear factors involved. However,it is recognized that the existed friction mechanism cannot fully reflect the formation process of friction because of ignoring some important influencing factors,such as temperature,elastic-plastic deformation and die wear. In addition,when constructing the friction model,the accuracy of model is not high because the correlation among various factors is not taken into full account. Therefore,the influences of macro and micro factors on the evolution process and formation mechanism of friction in stamping should be considered comprehensively,and a dynamic friction model with multi-factor coupling should be established,which is an important way of studying the formation mechanism of friction in stamping for sheet metal in the future.
