内容記述 | Blank holder force (BHF) is one of the important process parameters for successful sheet metal forming. Variable blank holder force (VBHF), that the BHF varies through the forming process, is recognized as an advanced forming technology. It has also been reported that segmented VBHF (S-VBHF) is valid to a complex shape forming, but the optimal S-VBHF trajectories are rarely discussed. In addition to BHF, blank shape has an influence on the product quality. The blank shape minimizing the earing is still an important issue in sheet metal forming. Simultaneous optimization of both segmented VBHF trajectories and blank shape is proposed in this research. Numerical simulation in sheet metal forming is so intensive that a sequential approximate optimization is adopted for the simultaneous design optimization. Based on the numerical result, the experiment using a servo press is carried out. It has been confirmed from the numerical and experimental result that the proposed approach is valid. | |||||
