| Outline of Final Research Achievements |
The flow-induced vibration for flexible thin plates and membranes surrounded by a fluid flow is an important engineering topic in the state-of-the-art manufacturing technology for the functional flexible membranous products, such as rollable solar panels, LED panels and so on.
We proposed an alternative analytical method for a description of the fluid-structure interaction problem based on the canonical theory for the constrained system. The proposed method is inspired by a numerical approach for multi-body system dynamics. In addition, this study developed a stability analysis method for a prediction of the flow-induced vibration. Then, the boundary condition for pressure, widely used in this problem, was verified by prospective vibration behavior. The proposed method was validated by comparing with results in the literatures.
