摘　　要：利用有限元理论和计算机手段,对液压成形工艺生产薄壁圆管局部变方管进行了模拟分析,在正确处理各种边界条件和载荷路径下,得到了管件的变形过程、等效应力分布和管端位移等一系列物理场参数;同时也发现管内压力和轴向压力之间的配比关系是零件成形的重要参数。本研究结论可为实际加工该类工件提供理论依据和生产指导。This paper focuses on hydroforming of rectangle in the middle of a tube.The numerical simulations were carried out for the tube processing.The controlling of hydroforming process mainly depended on processing parameters such as loading path and boundary conditions.The deformation process,distribution of equivalent stress and feeding displacement were obtained.The matching between internal pressure and feeding loading was found to be an important parameter for part forming.The results can provide reference for the practical forming
