Title: Numerical simulation study on the process of multi-point stretch-forming for sheet metal parts
Abstract: Forming defects have an important impact on the forming quality of sheet metal. Based on finite element software, the process of multi-point stretch-forming was simulated. The creation of finite element model, the choice of material model, the establishment of boundary conditions and the treatment of contact friction and so on were carried out. With the changes of technical parameters, multi-point stretch-forming is made further understanding, the potential forming defects may be predicted, the proper technical parameters are chosen to restrain or eliminate forming defects, and consequently the forming quality of the parts and efficiency of manufacture are improved. These results provide significant guidance to the practical application of multi-point stretch-forming technique.
