This research clarified the characteristics of the deformation and the dynamics of the gossamer multi-body structure, which consists of the gossamer structure, i.e. thin membrane and cable, and its back-up structure such as the spacecraft main body. The research includes the formulation of the theory, numerical simulation, and the ground experiment. The proposed theory and the numerical method were applied to the design and the development of the small solar sail demonstrator “IKAROS” developed by JAXA, and their validity was proved in space by comparing with the flight data of IKAROS. Finally, a new analytical method of gossamer structure was proposed to contribute to put the structure into practical use.

本研究明确了由薄膜、缆索等游丝结构及其航天器主体等支撑结构组成的游丝多体结构的变形和动力学特征，研究内容包括公式化。所提出的理论和数值方法应用于JAXA开发的小型太阳帆验证器“IKAROS”的设计和开发，并在太空中证明了其有效性。最后通过与IKAROS飞行数据的对比，提出了一种新的游丝结构分析方法，为该结构的实际应用做出贡献。
