Modal Energy Analysis (MODENA) is a new method which focuses on structural-acoustic coupling problems in recent years. It can predict the energy response of the system quickly and accurately. An algorithm that integrates Finite Element (FE) and MODENA is proposed to solve the structural-acoustic coupling analyses of complex dynamic systems when modes information cannot be solved by analytical ways. The proposed algorithm is applied to a complex structural-acoustic coupling system. Results show that the FE-MODENA method gives a fine estimation to the structural-acoustic response analyses compared with Dual Modal Formulation results, especially when considering multi-point random excitation.
