摘　　要：确定了斜轧磷铜球轧辊孔型曲面方程,通过VC++编程得到轧辊孔型曲面上的特征曲线.利用Pro/E的曲面建模功能建立了轧辊的三维实体几何模型.利用DEFORM-3D软件,采用三维刚-塑性有限元法对斜轧磷铜球进行了数值模拟,获得轧件变形区的应力-应变场分布规律.The equation of groove surface for skew rolling copper balls was defined, and the characteristic curves were obtained by VC ＋ ＋ programming. A three-dimensional entity model of the roll was established by Pro/E software. The three-dimensional nonlinear finite element method was used to numerically simulate the metal forming process of copper balls by DEFORM-3D analysis software, and the stress and strain distributions were presented from this simulation.
