摘　　要：应用动态显式有限元法,建立了T型管液压成形分析模型,对不同加载条件下的模拟结果进行对比,分析了轴向载荷的作用,探讨了最佳载荷曲线的确立原则.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.
