Abstract：

The three-dimensional finite element model of the spinning process for cone parts was established based on ANSYS. The regularities of stress-strain distribution were obtained through the simulation. The influence of deviation and roller feed rate was analyzed. The reasons of defect, such as crack and peeling were explained and some measures were given. The results show that the maximum principal stress under positive deviation condition is usually larger than that under zero deviation and negative deviation conditions, and the workpiece cracks easily under positive deviation. The effective strain on the outer surface is larger than that on the inner surface, and the peeling of the workpiece appears easily when the roller feed rate is comparatively large.
