This paper presents the results of numerical solution of the 3D spectral problem on natural vibrations of two parallel identical rectangular plates interacting with a quiescent fluid confined between them. Based on the developed finite element algorithm several examples have been considered to analyze the influence of the fluid height and boundary conditions on the natural frequencies and vibration modes.
