| Abstract: | By the finite element numerical simulation of multistep forming for sphere surface,its key technology,the behaviors of the forming process were analyzed.The defects liable to happen and the key problems have to be solved in the forming process were explored in detail.The simulation results show that the multi-step forming can optimize the deformation path of sheet metal,make the deformation more uniformly,effectively restrain wrinkles and improve the deformation capacity of sheet metal. |

| Keywords: | materials synthesis and processing technology multipoint forming multi-step forming numerical simulation deformation path |
