摘要 采用三维刚塑性有限元对筒形件反旋进行了分析。建立了筒形件反旋的三维分析模型,获得了旅轮作用区域和其周围区域的应变速率和应力的分布,较好地解释了工艺的变形规律,计算得到了旋轮前锥角对旋压三分力的影响关系以及使总旋压力最小的旋轮前锥角。有限元分析获得的变形区的分布与试验结果相符。 Backward spinning is analyzed by 3D rigid-plastic FEM. A 3D mechanical model for backward spinning is presented in this paper. The distributions are obtained of strain-rate and sterss in the contact area of the roller and its adjacent area. The results can well interpret the principle of backward spinning deformation. The relationship between the roller angle and three components of spinning force has been found out,and the optimum roller angle,when the general spinning force gets to the minimum va1ue, is calculated. The distributions of deformation area obtained by FEM agree with the experimenlal result well.
