摘　　要：为了验证压边圈减轻孔开设的形状和减轻质量效率是否合理,采用ABAQUS软件的tosca模块对其进行拓扑优化分析,通过最小化应变能响应和移除不同的体积目标约束,获得了优化后的形状、应力和变形位移大小,指出了实际减轻质量设计的不足,同时为汽车模具压边圈及其他部件结构的轻量化设计提供了理论依据。In order to verify reasonability the shape and weight reduction efficiency of the lighten⁃ing hole in blank holder,the tosca module of the ABAQUS software was used to analysis the topol⁃ogy optimization.By minimizing the response of strain energy and removing different volume tar⁃get constraints,the optimized shape,stress and deformation displacement were obtained,which pointed out the shortcomings of the actual weight reduction design,and provided a theoretical ba⁃sis for the lightweight design of the blank holder and other parts of the automobile die.
