Development of an analysis method for acoustic–structural coupling systems using the BEM for the acoustic field: The validity of the method developed and comparison with the FEM acoustic field

A formulation is developed for the analysis of coupled acoustic–structural systems using the boundary element method (BEM) in order to apply the coupled method to the open field in addition to the closed field. In this formulation the most general mode superposition method by Ma-Hagiwara, namely, th...

description A formulation is developed for the analysis of coupled acoustic–structural systems using the boundary element method (BEM) in order to apply the coupled method to the open field in addition to the closed field. In this formulation the most general mode superposition method by Ma-Hagiwara, namely, the high- and low-order truncatable mode superposition method, is used where the higher and the lower modes are truncated. The propriety of this formulation is verified by comparing it with a theoretical solution in a one-dimensional problem and with the solution by a method in an interior noise problem, which was developed using the finite-element method (FEM).
