Abstract
The structural intensity analysis, which calculates vibration energy flow from vibratory velocity and internal force of structures, can give information on source power, dominant transmission path and dissipation of vibration energy. In this study, the structural intensity analysis for a 4,100 TEU container carrier is carried out. Its purpose is to investigate how to effectively change the vibratory response of superstructure by the structural modification using the information of structural intensity. From the various numerical studies, the structural modification for dominant transmission path of vibration energy from the excitation source to the superstructure is regarded as one of the most effective methods in changing the natural frequency and its resonant response of the superstructure.
