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

关于如何组装成千米量级的巨型空间结构的研究很少。在本项目中，我们针对未来空间太阳能卫星(SSPS)的应用，对建造和维护大型空间结构的方法进行了可行性研究。我们的项目分为三个子主题：(1)自组装系统设计，(2)结构模块设计和(3)规划系统设计。在(1)中，我们设计了一种新的可展开张拉整体结构，它可以存放在适合机器人搬运的紧凑的六角形壳体中。研究了在国际空间站采用日本模块进行部署的设想。在(2)中，提出了几种不同的充气结构构件设计方案。对充气管和可展开(折叠)膜的力学性能进行了详细的评价。还研究了充气管和可展开膜的结构复合材料。(3)研究了自组装、自修复算法和故障检测算法。

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.
