球形容器无模液压成形新工艺自1985年提出以来[1]．在理论分析、实验研究和工程应用方面取得了许多成果。目前制造的球形容器最大直径达9．4m，最大壁厚达24mm，应用于供水，液化气和建筑装饰等领域并已扩展到椭球等非球类壳体的液压成形[2，3]。在此基础上，本文提出一种新的?
Ball-shaped container without mold hydroforming new technology since its inception in 1985 [1]. In theoretical analysis, experimental research and engineering applications have made many achievements. Currently, spherical vessels with a maximum diameter of 9.4 m and a maximum wall thickness of 24 mm are used in the fields of water supply, liquefied gas and architectural decoration, and have been extended to the hydroforming of non-spherical shells such as ellipsoids [2,3]. On this basis, this paper presents a new?
