摘要：

基于刚塑性有限元法基本理论，借助通用三维有限元软件Deform-3D V6.0对花键冷滚压成形全过程进行了三维动态分析，获得了成形力-行程曲线、等效应力和等效应变的分布情况。结果表明，变形主要发生在工件表层的一定范围内，工件中心处基本不产生变形，等效应力最大出现在滚压轮与工件接触的两个位置,最大等效应变出现在花键齿槽处。该研究为花键冷滚压成形工艺研究提供了理论依据。

Based on the basic theory of rigid-plastic finite element method (FEM), a three-dimensional dynamic FE simulation model of the whole process of spline cold roll forming was analyzed by means of a common three-dimensional finite element software Deform-3D V6.0. The force\|stroke curve,distribution of equivalent stress and equivalent strain of spline cold roll forming were obtained. The results show that the deformation mainly occurs in a certain range of the workpiece surface，and nearly no deformation occurs in the center zone.The maximum equivalent stress occurs in two-locations where the roll wheel and part contact, and the maximum equivalent strain occurs in alveolar of spline. The research provides the theoretical basis for study on spline cold forming process.
