Abstract
Vibroacoustic systems, involving cascade structures mutually coupled through partially open/close acoustic cavities, are commonly seen in various applications. The modeling of such systems is challenging since the two adjacent acoustic domains separated by the partial partition are connected both structurally and acoustically, where the continuity conditions along each separation interface cannot be conveniently described. A formulation based on Patch Transfer Function (PTF) approach may potentially offer the solution for tackling such problems, provided that the treatment of the aperture can be integrated into the PTF framework. In this paper, the concept of "Compound Panel" is proposed, so that the parallel coupling between two adjacent acoustic domains can be converted into serial connection. In the proposed formulation, an aperture is modeled as equivalent virtual panel element, to be combined with the structural panels (either perforated or solid) to form a compound panel subsystem. This formulation simplifies the assembling procedure, while enhances the capability of the PTF method in handling system complexities. By investigating into several typical configurations, the versatility and efficiency of the method as well as the underlying physics are demonstrated.
