摘要：

针对航空航天、核能工程与新能源汽车等国家重大科技工程领域中具有大膨胀率及大截面变化比等复杂结构特征的管类零件，开展将液压成形与机械力加载相结合的管材液力成形技术的研究。根据零件几何结构特征和施加载荷方向的不同，将该技术进一步分为轴向加载、径向加载以及多向复合加载液力成形工艺。从工模具开发、有限元仿真、加载路径优化及在典型复杂管类零件上的应用等多个方面，对管材液力成形技术的研究进展进行阐述和介绍。结果表明，该技术通过结合外部的机械力作用，在降低成形时管材内所需液体压力及设备吨位的同时，还能够实现变形量高达近70%的复杂管类零件的整体成形，从而提高了产品的成形性能和表面质量，进一步拓展了液压成形技术在管材精密成形中的应用，为高性能金属复杂管类零件的开发提供了有效的技术支撑。

For the tubes with complex structural features such as large expansion ratio and large cross-sectional change ratio in major national science and technology engineering fields such as aerospace, nuclear energy engineering and new energy automobiles, tube hydro-mechanical forming technology (THMF) was studied by combining hydroforming with mechanical force loading, and the THMF could be classified to axial loading, radial loading and multi-directional compound loading according to the differences of structural characteristics of parts and loading directions. Then, the research process of THMF was systematically explained and introduced in the aspect of development of tools and dies, FE simulation, optimization of loading paths and application in typical complex tubes, etc. The results show that by combining with the external mechanical force，THMF can reduce the internal liquid pressure in tube and equipment tonnage during forming, and realize the integral forming of complex tubes with a deformation amount of nearly 70%. Therefore, the formability and surface quality of parts are improved, and the application of hydroforming in precision forming of tube is further extended, which provides effective technical support for the development of high-performance metal complex tubes.
