Forced Vibration and Sound Radiation of a Rectangular Plate with Viscoelastic Boundary Support

Abstract

A method for the forced vibration and sound radiation of a rectangular plate with viscoelastic boundary supports is proposed. The method is based on damped complex modes analysis method. Using the damped complex modes of the plate system, the modal equation of the plate motion becomes completely uncouped. The sound radiation pressure is obtained by numerical integration of the Rayleigh integral. Effects of the viscoelastic boundary supports on the vibration response and the radiated sound pressure of the vibration plate are discussed by an example.
