Abstract: The deformation mechamsm of cold spinning disc-shaped seal is analysed according to FEM theory. The software ANSYS is implemented to simulate numerically the deformation .The distribution law of stress and strain is obtained vvhen the seal moves. The efiect of stress and strain or deforraalion is analysed and the spinning foree is calculated. The research provides the optimisation of process vvith parameter effective methods and reliabte foundaiion.
