| Abstract: |
| Based on the finite element simulation and process test, the spinning forming experiment of 3A21 aluminum alloy tubular parts with circumferential inner ribs was carried out. Analyzed the forming condition and stress change rule of the inner rib under different spinning clearance and feed ratio. Combined with the numerical simulation test, the surface peeling, cracks and other defects of the workpiece during the process of forming were preliminarily analyzed. The analysis provides a theoretical guidance for the control of spinning defects with ring inward ribs. |
