Abstract
A new procedure to formulate and analyze the free vibration problem of structural-acoustic coupled systems is suggested. The system equation s are formulated utilizing the concept of the equivalent mass source. The modal expansion method and a matrix transformation technique are u sed to solve the system equations to obtain the natural frequencies an d modes of the system. The procedure is verified by comparing its resu lt with the exact solution of a one-dimensional coupled system. Parame ters dictating coupling effects are also identified and discussed.
