钛合金管被广泛应用于航空航天等领域的液压管路系统中。然而，高的屈弹比会导致钛合金管冷弯后产生显著的回弹，而过度回弹会严重影响管路的装配及密封性能。为此，对近年来钛合金管冷弯回弹及其控制问题的研究工作与成果进行了综述，重点介绍了研究钛合金管冷弯回弹问题时通常采用的两种方法及相应的研究成果，主要包括理论解析法和有限元模拟法，并指出应对钛合金管材小角度下的弯曲及回弹进行深入研究，进一步提高管材弯曲理论研究的水平，将有限元模拟法与实验验证充分结合。

Titanium alloy tubes ( Ti-tube ) have been widely used in hydraulic plumbing systems of aircraft and spacecraft.However, significant springback of Ti-tube occurs after unloading due to its high ratio of yield strength to Yong’ s modulus.The severe springback affects the connection and sealing performance of tubes with other parts. Therefore, the present research and findings of Ti-tube springback as well as its control are reviewed, while the methods of theory analysis and finite element simulation are introduced respectively.Finally, it is pointed out that bending and springbank beheavior under small angle for Ti-tube needs further investigation, and the level of theory research also needs to be improved.Besides, the methods of finite element simulation and experiment can be combined during the research.
