Abstract：To mitigate the heavy simulation work of error test for blank shape, the polygon blank shape with high practical value in sheet metal forming process was optimized for design. Intelligent experiment design, moving least-square and adaptive updating method were used to establish response surface surrogate model and to optimize polygon blank shape. The corresponding optimization programs were also developed. An actual automobile side wall inner-top panel was taken as polygon blank shape for intelligent design. The optimization forming effect was compared with that without optimization. The results show that the risk of rupture and wrinkling is obviously decreased by optimization with good forming shape. The proposed method can improve efficiency and precision of optimization design with increased intelligent degree, and can speed up die design process with decreased production cost.
