概要	This paper deals with vibration analysis and experiments of the self-excited vibration in a flow dynamics conveying machine. In this paper, unstable conditions of the self-excited vibration and vibration characteristics are examined by vibration analysis and experiments. Critical flow rate is calculated by using the root locus and Routh-Hurwitz stability criterion based on the characteristic equation. Experiments conducted with system which the plate floated by an air, and frequency and vibration amplitude of self-excited vibration are measured. Based on the result, instability regions are examined. Moreover, the unsteady fluid force acting on the plate is examined by measuring pressure between air bar and plate, and the local work by the unsteady fluid force on the plate surface is clarified.
