Kurzfassung
Vibro-acoustic coupling between structural and acoustic domains via the Finite Element Method can be tackled using different reduction techniques. This study compares three coupling approaches within the displacementpressure formulation: standard modal coupling, modal coupling with static corrections, and Craig-Bampton vibro-acoustic coupling. A symmetrization procedure is introduced for all methods, facilitating the computation of coupled vibro-acoustic modes. Through a representative example, the methods are evaluated in terms of performance and computational efficiency, benchmarked against the physical, non-reduced coupling approach.
