| Abstract: | According to the dimension and deformation of realistic workpiece, the math model of spinning sealing workpiece was set up, and ANSYS software was applied for 3D numerical simulation of forming process of sealing workpiece. The deformation mechanism was analyzed, and the defects and reasons of sealing workpiece in the numerical simulation deforming were analyzed. It shows that effective stress and strain is bigger with the increase of thickness, the maximum first appears in the circular section, and crack defects comes easily. |
