Vibrations may occur to a machine and structures under the influence of a fluid. In this analytical method, dynamic stability of rectangular flexible plate is estimated in three-dimensional cantilevered channel. Channel wall is considered rigid. The fluid assumed as an ideal flow in a subsonic domain, and the fluid pressure is calculated using the velocity potential theory. The unsteady fluid pressure is determined by using the integral equations under the boundary conditions in the Fourier space. Changing the mass ratio, aspect ratio and gap ratio, the critical flow velocity and vibration distribution of the plate are investigated.
