| Abstract | In order to grasp the springback rule of TRB (tailor rolled blank) parts after forming, the springback behavior of TRB was investigated by integrating such three means as theoretical research, numerical simulation and stamping experiments. Fundamental theories of springback were analyzed. The stamping and springback processes of annealed 1. 2/2. 0 mm TRB, 1. 2 mm and 2. 0 mm plates for U-channel were simulated, and the simulation results were compared with the experiments. The results indicate that the springback of TRB falls in between those of the 1. 2 mm and 2. 0 mm plates. It is desirable for the TRB U-channel to have die clearance of 1. 1 times maximum blank thickness and friction coefficient of about 0. 12, and longer thickness-transition zone is preferable. The simulation data demonstrate reasonably good agreement with the experiments. |
