摘要: 近年来,在轨服务技术日趋成熟,因此在空间技术研究领域在轨组装受到了较高的关注度。研究了一种大折展比高刚度索杆张拉式六棱柱组装单元及三爪式对接接口机构,并对其运动学及动力学特性进行了研究。首先,提出并设计了一种新型的空间结构组装单元和一种结构为三爪式的对接接口,进行在轨组装时可应用该接口。接着,分析了空间结构组装单元的运动学特性,验证了组装单元具有良好的展开与锁定功能。最终,通过对大型结构体模型进行有限元分析,发现了结构体的基频受到多个参数的影响,通过进一步的分析得到了具体的影响关系和灵敏度,为在轨组装空间大型结构体的设计奠定了基础。

Abstract: In recent years, in-orbit service technology is becoming more and more mature, so in-orbit assembly has received great attention in the space technology research field. In this paper, a kind of cable-strut tension hexagonal prism assembly unit with large deployment ratio and high stiffness and a kind of three-claw-type docking interface mechanism are studied, and their kinematic and dynamic characteristics are studied. Firstly, a new space structure assembly unit and a three-claw docking interface are proposed and designed, the interface can be used for in-orbit assembly. Then, the kinematic characteristics of the spatial structure assembly unit are analyzed, and the good deployment and locking functions of the assembly unit are verified. Finally, according to the finite element analysis of the large structure model, it is found that the fundamental frequency of the structure is affected by many parameters, and the specific influence rules and sensitivity are also shown under the further analysis, which lays a foundation for the design of the space large structure in-orbit assembly.

Key words: in-orbit assembly, hexagonal prism unit, structure design, docking interface, kinematics, dynamics
