概要	This paper presents an analysis and experiments on the self-excited vibration of a floating plate and a support structure. In this study, the analysis model and the experimental apparatus have elastic support structures and multi air supply holes. The vibration characteristics and the unstable conditions of the self-excited vibration were examined through the analysis and the experiments. As a result, a good agreement is found between analytical and experimental results. Moreover, the local work done by the unsteady fluid force is shown, and the instability mechanism is discussed. Lastly, the influence of the damping ratio was examined through the experiments using friction damper and the analysis, and the effectiveness is discussed.
