Abstract

It is well established that fluid flow can have significant effects on structural acoustic behavior, along with the fact that induced coupling between discrete modes of vibration becomes significant as flow velocity increases. Work in this area has been confined to flows in air, over unloaded structures, with the effects on sound radiation efficiency, kinetic energy, and sound power radiation quantified and compared for various flow speeds. The purpose of this work is to study the effects that plane stress has on these structural acoustic phenomena. Theoretical development of the equations governing the vibration of a simply supported plate subjected to in-plane forces in an infinite baffle and an aerodynamic system that models a semi-infinite flowing medium along with the method for coupling these systems is included. Computational results are presented illustrating the behavior of the uncoupled coupled effects on the sound power radiation from the plate in both subsonic and supersonic flows, for a variety of loading cases.
