摘要：

The basic theory of statistical energy analysis (SEA) method used for vibration and noise analysis in high frequency domain is based on the energy transmission between the subsystems of the whole structure. The paper focuses the modeling method mainly on setting up the subsystems and tries to find the relations between the different ways and their results to set up the key subsystems. The feasible domain of SEA for dynamic analysis of container ship is identified by presentation of the modal density of subsystems in SEA model. The computational results show the transmission mechanism of vibration and air-borne noise distribution in cabins and structures and will give a guidance for the acoustic and anti-vibration design of large container ships.
