It is important to clarify characteristics of dynamic problems of structural systems loaded with liquid in the case where the systems are subjected to shock load or engine vibration. The purpose of this investigation is to develop the method by which to analyze the systems' coupled vibration and acoustic problems in order to reduce vibration and sound output of such systems. We developed the method by which to analyze dynamic problems of the coupled solid, liquid and air systems using the finite element method (FEM). The proposed analysis method was applied to vibration and acoustic problems of the twin cabin partially filled with water. We also carried out a series of experiments by using the twin cabin model. The validity of the proposed method and the applicability of the developed FEM programs were demonstrated by comparison with experimental results.
