摘　　要：三通管是广泛应用于汽车、化工和家用电器的零件,其中,T 型三通管已有不少学者进行了研究。本文在 T 型三通管成形的基础上,对某 Y 型三通管液压胀形工艺进行了分析和有限元数值模拟,计算了成形过程中的胀形力、轴向载荷和平衡力,初步确定了成形工艺参数和加载轨迹;而后采用有限元数值模拟分析了不同加载路径 Y 型三通管的成形情况,以及在不同加载路径下的内压力、轴向进给量、支管高度和零件壁厚分布等成形情况,得出了 Y 型三通管合理的加载路径。Tri-branch tube is widely used.for automobile, chemical engineering and household electrical appliance. And T-branch tube has been studied. In this paper, based on some T- branch tube forming technology hydraulic bulge process of Y-branch tube is studied and its finite-element numerical simulation is carried on. Acquired the bulging force, axial load and equilibrant, the paper confirms the forming technical parameters and load locus; then it analyzes the formation of Y-branch tube with different loading routes and others, such as internal pressure, axial amount of feed, branch height and distribution of part wall thickness. Finally, it concludes the proper loading route of Y-branch tube.
