| Outline of Final Research Achievements |
In this study, analysis method for a system with a very flexible structure is proposed and the method utilizes the analogy between the behavior of rigid body collision phenomena and system with very flexible structure. Comparison of numerical analyses by the proposed method and nonlinear finite element method as conventional method shows a good correspondence and the proposed method shows good computability compared to nonlinear FEM. Moreover, good correspondence between the experimental results and the numerical analysis results are obtained. Furthermore, by utilizing the good computability of the proposed method, numerical optimization of a system having a flexible structure can be easily performed and the proposed method is applied to the optimization problem of the structure of a spacecraft having a tether.
