barrel shutter

Based on the blank stamping simulation software Dynaform, the FE model of the automobile circle tubular was established, with which the influence of different shape of drawbead on the stamping quality was analyzed, and the forming limit diagrams before and after drawbead optimization were obtained.

以板料成形仿真软件Dynaform为平台,建立了圆桶形件有限元模型。
