Acoustic Excitation of Structures Analyzed by the Statistical Energy Method

Abstract

This paper presents the application of the Statistical Energy Method to the analysis of the acoustical response of spacecraft structures. The structures are assemblages of flat plates and cylinders interconnected in several ways. The analytic results were verified against a comprehensive test program in which representative structures were exposed to a reverberant sound field. In general, the correlation between test results and theoretical predictions was good, and indicates the manner in which the Statistical Energy Method can be used to obtain predictions in a relatively simple manner.
