摘　　要：针对金属薄片通过弯折、冲压成型等变形过程,提出关于金属薄片变形的快速、有效的自适应仿真框架。首先基于金属薄片材料的几何及物理特性,修改自适应重新网格化的加劲肋约束;并对网格的最佳尺寸约束进行改进,以模拟金属的高延展性;最后给出简单高效的金属薄片自适应变形仿真的系统框架。实验结果表明,该框架可适用于任何金属薄壳。Aiming at the deformation process of sheet metal by bending and stamping , this paper proposes a fast andeffective adaptive simulation framework for sheet metal deformation. Firstly , based on the geometrical and physicalproperties of the metal foil material , the adaptive re-meshed the stiffening rib restraint is modified. Then , the optimal size constraint of the mesh is modified to simulate the high ductility of the metal. Finally , a simple and efficient system framework for adaptive deformation simulation of sheet metal is presented. The experimental results show that theframework can be applied to any metal shell.
