Abstract：

The study object of outer panel blank of door was optimized based on the platform of finite element simulation technology, and the effectiveness of improving material utilization and reducing production costs in the wave edge expanding and cutting was verified. The finite element simulation result shows that there is no wrinkling and cracking during the forming of cutting pieces for wave edge. When the actual verification was conducted, the wave edge expanding and cutting was adopted, and the obtained pieces formed by stamping were the same as that of finite element simulation and without any problem. It brings the following conclusion that taking wave edge expanding and cutting, the processes of outer panel of door will not be increased and without any problem in forming, and the weight of needed blank is decreased from 16.7 kg to 15.8 kg as well as the material utilization is increased from 40.3% to 41%. Therefore, the greater economic benefits are obtained without production problem by mass production, and other stamping parts can apply the above method.
