| Research Abstract |
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.
