| Abstract: | As an important plastic working technique,sheet metal pressing is broadly applied in industry field especially in automobile manufacturing.The important situation in automobile manufacturing of sheet metal pressing and the level of the molding process of automobile pressing parts at home and abroad have been reviewed.The state-of-art,theory foundation and some special software in finite element are discussed.In the pressing process,the sheet often appears wrinkle?crack and rebound.Through analyzing the molding process of typical automobile pressing,it is proved that the numerical simulation in finite element will has the ability to forecast the forming defect.The paper points out that numerical simulation is playing more and more important action in pressing process. |
