Abstract：

The springback process of forming for transmission belt of clutch was simulated by Dynaform, the distributions of stress before and after spingback were analyzed, and the maximum stress values at round corner before and after spingback were 871.805 MPa and 339.947 MPa respectively, so the reduction of stress resulted in the blank springback. The influence of bending angle, thickness of blank and die clearance on forming height of transmission belt was studied. The results show that forming height of transmission belt increases with the increase of bending angle and die clearance, while decreases with the increase of thickness. Additionally, forming die of transmission belt was designed and verified by the experiment, the range of error between experiment and simulation is 7.55%-9.18%，which shows good agreement. When the die clearance is 1.1t, the experimental value of forming height is 4.98 mm, which meets the design requirement of 4.9-5.45 mm, and the error between experiment and simulation is 8.84%.
