| Abstract: | The program for numerical simulation of sheet metal hydroforming based on LS-DYNA was developed by using VB6.0, the appropriate mechanics model for hydroforming process was built up. The numerical simulation of a motorbike tank was made to test the developed program. The result shows that the developed program can solve the problems including boundary conditions, and the load paths of blank holder force and hydraulic press, by using it, the users can avoid the heavy job in modifying the parameters for simulation again and again. |
