摘　　要：建立了符合实际多道次普通旋压三维仿真模型,在进行毛料多道次普通旋压成形过程有限元模拟与实验验证的基础上,研究旋轮轨迹与方式对旋压件成形过程及质量的影响。结果表明,轨迹的变化对成形质量有较大的影响,在直线轨迹、圆弧轨迹、渐开线轨迹3种轨迹中,渐开线轨迹对成形质量最好,轨迹有渐压和无渐压,均有其各自的优缺点,需要综合利用,可得到优越的旋压轨迹。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.
