The numerical simulation of metal sheet forming is important in stamping production and die design.Based on software eta/DYNAFORM,the phenomenon of wrinkles and cracks produced during the forming of upper cover plate is simulated and the reasons of defect forming and the influencing factors of defects is analyzed.The problems relating the drawing quality of the upper cover plate is solved successfully through the regulation of the blank holding force and the utilization of the drawing beads.
