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.

研究了由薄膜和索组成的游丝结构及其支撑结构（航天器主体）组成的游丝多体结构的变形和动力学特性。研究内容包括理论推导、数值模拟和地面试验。将所提出的理论和数值计算方法应用于日本宇宙航空研究开发机构（JAXA）研制的小型太阳帆演示器“IKAROS”的设计和研制，并通过与IKAROS的飞行数据对比，验证了理论和数值计算方法的有效性。最后，提出了一种新的游丝结构分析方法，为游丝结构的实际应用提供了参考。
