概要	<p>This paper presents experiments and an analysis on the self-excited vibration of a plate on air flow and a support structure. The instability conditions and the vibration characteristics are examined using a theoretical analysis considering the effect air compressibility in a chamber. The system's characteristic equation is derived from the plate motion and the support structure motion coupled with equations of the gap flow between the plate and the support structure. The stability of the system is clarified by using the root locus. Moreover, the local work by the fluid force on the plate surface and the support structure surface is clarified by the energy analysis. Lastly, the unstable mechanism of self-excited vibration is discussed.</p>
