| Abstract: | Numerical analysis of pre\|forming process design is proposed in hydroforming automobile subframe.By using the software HydroFORM\|3D based on rigid\|plastic finite element method (FEM) and Oyane's fracture criterion,a modeling approach is put forth,and the theoretical result of pre\|forming process design is presented which is mainly referred to the determination of the initial tube size.The theoretical analysis shows that the suitable initial tube size for the pre\|forming process condition is favourable to perform a good hydroforming process of automobile subframe. |
