Introduction
The review of investigations related to the vibration plate + fluid systems was made in
papers [1, 2] and it was noted therein that until recently there was not any study in this field made
within the utilizing of the linearized exact equations of motion. In the mentioned sense the first
attempts were made namely in the papers [1, 2] in which the frequency response of the system
consisting of the elastic [1] and viscoelastic [2] plate and the half-plane occupied with compressible
viscous fluid was studied. Under these studies the equations of motion for the plate were written by
utilizing the exact linearized equations of elastodynamics and the equations of motion of the fluid
were written by utilizing the linearized Navier - Stokes equations.
The other considerable aspect of the investigations regarding the
dynamics of the plate-fluid
systems is a dynamic response analysis plate-fluid systems induced by a moving load. Results of
these investigations are applied for construction of the floating bridges and for determination of
their efficiency. As an example for such investigations it can be presented studies carried out in
papers [3 - 5] and others listed therein. However in these investigations the fluid reaction to the
plate (i.e. to the floating bridge) is taken into consideration without solution of the equations of the
fluid motion. It is evident that the approach employed in [3 - 5] is very approximate one and cannot
answer the questions how the fluid viscosity, fluid compressibility, plate thickness and the moving
velocity of the external force act on the “hydrostatic force” acting on the plate and on the fluid flow
velocities. To find the answers to these questions it is necessary to solve the corresponding coupled
fluid-plate interaction problems within the scope of the exact linearized equations described to the
plate and fluid motions. In the mentioned sense, in the present paper the first attempt is made for
solution to the problems related to the dynamics of the moving load acting on a system consisting of
the metal elastic plate and half-plane filled with compressible viscous fluid.
