中文摘要： 介绍了薄壁管件被动液压成形的基本原理及其特点，基于LS-DYNA动力显式有限元分析软件Dynaform5.6对薄壁管被动液压成形进行了模拟仿真，针对成形过程中的轴向进给与内压力匹配关系、以及轴向力与内压力的应力比取值区间展开研究，得到不同工艺参数下薄壁管件被动液压成形工艺的成形性能参数表，并对仿真结果进行了分析。
英文摘要： The paper introduced principles and characteristics of Thin-walled tube passive- hydroforming, based on LS-DYNA the finite element software Dynaform5.6 simulate the thin-walled tube passive- hydroforming, researched the axial feeding and pressure match relation of forming process and the stress range of axial force and internal pressur, obtained formability parameters of thin-walled tube passive-hydroforming process with different process parameter,and ansys the simulation results.
