초록
The draw, trim, flange, and cam forming processes of automotive fender panel are simulated, focused on the springbacks. Simulation results are compared with field try-out. In order to compensate the differences between simulation and try-out, the draw bead shapes in the simulation are modified and the accuracy of the simulation is improved by comparing blank draw-in amounts. The spring-backs after formings are also found in the simulation. Finally, the simulation procedures for analyzing the springbacks in all stamping processes are established.
