FEM Simulation and Optimization of Process Parameters for Tube Hydroforming
The finite element software DYNAFORM was applied to simulate the whole tube hydroforming process. Two main failure types in the process of hydroforming are wrinkling and bursting. The strain distribution and thickness distribution at different process parameters were presented. Not only friction coefficient but also the effect of different matching of internal pressure and axial force was simulated and analyzed. In addition, the velocity of punch was considered too. The result has reference value for the variable cross-section tube hydroforming process research.
