针对多道次常规旋压成形的特点，基于ABAQUS/EXPLICIT平台建立了实用的有限元模型，研究了滚子轨迹对成形过程和旋压产品质量的影响。在直线、圆弧和渐开线三种滚子轨迹中，渐开线滚子轨迹对成形质量的影响最大，有压力滚子轨迹和无渐开压力滚子轨迹的作用不同，应分别采用。结果表明，滚子轨迹对成形质量的影响较大，得到了良好的滚子轨迹。
A practical FE model had been developed based on the platform ABAQUS/Explicit,which was in accordance with the forming characteristics of the multi-pass conventional spinning.The influence of roller-trace on the forming process and the quality of spinning product had been studied.Among the three types of roller traces including straight-line,arc,and involute,the involute roller trace is the best for forming quality.Roller-trace with and without gradual pressure play different roles and should be applied accordingly.The results show that the roller-trace has great influence on the quality of the workpiece and a good roller-trace is obtained.
