Abstract：

The finite element model for multiple-stages incremental forming process of sheet metal was built based on ANSYS/LS-DYNA platform. The forming process of vertical wall cylinder was simulated. The analysis was done on the aspect of motion law of node and correspondence of regional before and after the forming to find the reason that caused defect of circular bead. The key to avoid defect of circular bead is that the main forming of circular bead shall be finished in the forming way from bottom to top and rational deformation shall be reserved in the circular bead before this forming way being adopted. Defect of circular bead can be avoided by optimizing the tool path in the end.
