Self-assembly and Self-repair System of Membrane-Truss Complex for Space Solar Power Plant

如何将巨大的空间结构按千米顺序组装在一起，目前的研究还很少。在本项目中，我们针对未来空间太阳能卫星（SSPS）的应用，对大型空间结构的构建和维护方法进行了可行性研究。我们的项目有三个子主题：(1)自组装系统设计；(2)结构模块设计；(3)规划系统设计。在(1)中，我们设计了一种新的可展开的张拉整体结构，该结构可以存储在紧凑的六角形外壳中，适合机器人搬运。研究了假定日本太空舱在国际空间站的部署情况。在(2)中，提出了几种不同的充气构件设计方案。详细评价了充气管和折叠膜的力学性能。研究了充气管与可展开膜的结构组合。在(3)中，研究了自组装和自修复算法以及故障检测算法。

There have been very few researches dealing with how to assemble huge space structures in kilometer order. In this project, we have conducted feasibility study on a method of constructing and maintaining large-scale space structure aiming at future application for Space Solar Power Satellite (SSPS). There are three subthemes in our project : (1) Self-assembly system design, (2) Structural module design and (3) Planning system design. In (1), we have designed new deployable tensegrity structure which can be stored in compact hexagonal shell suitable for robot handling. The scenario of deployment assuming Japans module in International space station is also studied. In (2), several different design of inflatable structural members were proposed. Mechanical behavior of inflatable tubes and deployable (folded) membranes were evaluated in detail. Structural composite of inflatable tube and deployable membranes were also investigated. In (3), Algorithms for self-assembly and self-repair and failure detection algorithms were investigated.
