概要	<p>This paper presents experiments on the self-excited vibration of a plate supported by air pressure. In this study, the vibration characteristics and the unstable conditions of the self-excited vibration are examined through experiments. The unstable conditions considering the influence of shape and placement of an air supply port on the chamber surface was clarified. The unsteady fluid force acting on the plate (bottom surface) is investigated by measuring the unsteady pressure. The local work done by the unsteady fluid force is also clarified. Lastly, the unstable mechanism of the self-excited vibration is discussed based on the experimental results.</p>
