Abstract：

For the problem that both parametric modeling and die compensation can not be achieved in commercial software, based on VB, a parametric modeling and analysis platform for sheet metal forming process considering springback and die compensation was developed. Dynamic explicit algorithm was used to simulate the forming process and static implicit algorithm was used to simulate the springback on this platform. The die was compensated by the displacement adjustment method according to the springback deviation, the parametric modeling and analysis were achieved for similar parts, and the law of the influence of friction coefficient and die gap on springback deviation was obtained,and the ideal die face was also obtained, which showed the intelligence and efficiency of the platform.
