根据剪旋过程的实际情况进行了应力应变分析 ,对剪旋变形机理提出了新的见解 ,将剪旋变形区分为拉弯区和辗压变形区。前者的受力情况类似于胀形 ,后者为母线方向拉应力作用下的辗压变形 ,该区起主要减薄壁厚的作用。此外 ,本文利用Z形图对剪旋的各种状态进行了应力应变分析 ,并确定出了剪旋时最佳应力应变状态的区域。

According to the deformation of shear spinning on conical workpieces,the stress and strain has been analyzed and the new deformation mechanism has been put forward that the forming area of shear spinning should be divided into tension bending zone and rolling zone. The former is similar to bulge, but the deforming mode of the latter is rolling in which the stress is tensile in generatrix direction and the wall thickness are mainly reduced in this zone. In addition, by means of Z graph,the stress and strain of different shear spinning state has been researched and the optimum range of stress and strain has been gained.
