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-3DV6.0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, the 3D dynamic analysis of the whole process of cold spline forming by means of 3D finite element software Deform-3DV6.0 was carried out. The forming force-stroke curve, equivalent stress and equivalent strain The distribution of The results show that the deformation occurs mainly in the surface of the workpiece within a certain range, the workpiece center does not produce deformation, the maximum equivalent stress occurs in the rolling wheel and the workpiece in contact with the two locations, the maximum equivalent strain appears in the spline groove . The research provides a theoretical basis for the research of spline cold rolling forming technology.
