概要	This paper presents experiments on the self-excited vibration of multiple plates on supported by air pressure. The vibration characteristics and the unstable conditions of the self-excited vibration are examined through experiments. The experimental setup comprised the multiple plates supported by the pressure of air supplied from holes on the upper surface of a chamber. The dynamic stability of the multiple plates is affected by air the flow rate and the number plates. Therefore, in this study, the influence of the parameters on the dynamic stability of the system is investigated for a system. Furthermore, the unsteady fluid force acting on the multiples plates is investigated by measuring unsteady pressure, and the local work done by the unsteady fluid force is clarified. Lastly, the instability mechanism of the self-excited vibration is discussed based on experimental results.
