概要	<p>This paper presents experiments on the self-excited vibration of a weight on air flow and a trough. In this study, the vibration characteristics and the unstable condition in the case of the support structure as the trough model are examined through experiments. The experiment setup comprised the weight supported by the pressure of air supplied from slits on the upper surface of the trough, where the vibration characteristics were examined. The unsteady fluid force acting on the weight and the trough is examined by measuring unsteady pressure, and the local work done by the unsteady fluid force is clarified. Lastly, instability mechanism of the self-excited vibration is discussed based on the experimental results.</p>
