【Abstract】 Workpiece forming in the T-shaped tube hydroforming process takes place through internal pressure and axial load. If these loads are chosen poorly there will be failure in the workpiece involving wrinkle or bursting. A dynamic FEM model is built for the T-shaped tube hydroforming process. Through analyzing the different simulation results, the influence of axial load is discussed and the optimum loading profile is determined.更多还原
