Vibrational response features of a locally excited fluid-loaded plate with attached mass-spring oscillator systems

Abstract

Preston Smith and others have examined the radiation features of locally excited plates that are periodically supported by inertial masses. This presentation looks at the vibrational response and on-surface pressure field of a locally excited fluid-loaded plate that has one or more attached mass-spring oscillators. The analysis makes use of the "rational function approximation" (RFA) representation of the fluid loading effect first introduced by Diperna and Feit (J. Acoust. Soc. Am. 114(1), July 2003, pp. 194-199).
