Abstract：

On the basis of the elasto-plastic finite element method,ANSYS software is applied in order to simulate spinning deformation of the vessel head with thin wall thickness.The distribution of stress and strain on the sphere coronal and the first pass corner is obtained so as to acquire the basic law of plastic deformation of the spun workpiece.Analysis is laid on the influence of several main process factors on forming quality as well as failure problems of the spun part.The results show that the main failure pattern of cold spinning deformation of the vessel head with thin wall thickness is the wrinkling of outer flange.The effective measures which are taken to avoid wrinkling include increasing the rigidity of outer flange by bending edge,selecting the appropriate obliquity of the first pass and adopting small feed ratio.
