筒形件强力旋压时旋压力三个分量及其分布规律是确定设备功率及结构参数的重要依据。本文采用三维弹塑性有限元法对筒形件强力旋压工艺进行了分析 ,得到了正旋时变形区接触面上旋压力 3个分量的分布规律 ,计算结果与叶山实测结果吻合较好 ;同时得到毛坯内表面各节点的位移分布规律 ,为合理选择工艺参数 ,提高产品的尺寸精度提供了理论依据 The three components of the spinning pressure and their distribution during the strong spinning of cylindrical parts are the important basis for determining the power and structural parameters of the equipment. In this paper, the three-dimensional elasto-plastic finite element method was used to analyze the strength spinning process of the cylindrical part. The distribution of the three components of the rotating pressure at the contact surface of the normal rotating section was obtained. The calculated results agree well with the measured results. Get the displacement distribution law of each node on the inner surface of the blank, which provides a theoretical basis for the reasonable selection of the process parameters and the improvement of the product dimensional accuracy
