| Abstract: | Side-panel is the most complicated part of the automobile panel and it costs long time to get qualified part.A study case of the side-panel in drawing process was discussed based on sheet metal forming simulation.Some defects,such as cracks,wrinkle,skid line and surface deviation on the parts were introduced during the try-out and trial-production,and solutions were put forward based on FEM simulation.It will be helpful to the try-out and the optimization of the side-panel die. |
