Coupling Effect Analysis of 3D Interior Structural-Acoustic Problems Using Wave Based Method

Abstract:

This paper describes the basic concept of the new technique for the modeling of the structural-acoustic coupling between the pressure field in an acoustic cavity with arbitrary shape and the out-of-plane displacement of a flat plate with arbitrary shape. It is illustrated through a three-dimensional validation example that the new prediction technique yields a high accuracy. The effect of the cavity depth and the coupling interface area on the strength of mutual coupling interaction are discussed in detail.
