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 are examined through the analysis and the experiment. As a result, the vibration characteristics and the unstable conditions are clarified. Especially, it is shown that in-phase mode and anti-phase mode vibration occurs when the large spring constant and the large number of air supply holes. Moreover, theoretical results are compared with experimental results, and the difference is discussed. Lastly, effect of the damping elements is examined through the analysis.
