摘　　要：运用Deform-3D有限元分析软件对铜包铝复合线拉拔过程进行数值模拟,获得了拉拔过程中的轴向应力、径向应力及等效应变等的分布,分析了影响铜包铝复合界面强度、拉拔模具弹性变形及使用寿命的关键因素。这对在拉拔实际生产中提高铜包铝复合线材的质量、延长模具寿命具有一定的指导意义。The drawing process of copper-clad aluminum composite wire was numerically simulated by Deform-3 D finite element analysis software. The distributions of the axial stress, radial stress and equivalent strain were obtained in the drawing process. The key factors of affecting interfacial strength of copper-clad aluminum wire, elastic deformation and service life of drawing die were analyzed. This has certain guidance significance to improve the quality of copper-clad aluminum composite wire and to prolong the service life of the drawing die in actual production.
