Abstract

Substructure synthesis methods, which are applicable to the vibration analysis of large complex machine structures, are applied to acoustic analysis. At first, the frequency response spectra of sound pressure emitted from a fiat rectangular steel plate in a cubical steel box are analyzed by the finite element method or by the boundary element method. Comparing the calculated results with experimental ones, their accuracy is discussed. Next, the reduced impedance method and the component mode synthesis method, which are the substructure synthesis methods previously proposed by the authors for the vibration analysis of machine structures, are applied to acoustic analysis. The sound pressure frequency response spectra calculated by these methods are quite close to experimental ones.
