Description

The noise prediction using SEA(Statistical Energy Analysis) method in high-speed boats such as patrol boats, passenger boats, has been investigated theoretically and experimentally. In the development of the SEA model for a high-speed boat, it is important to define subsystems containing the engine-girder structure which vibration energy is transmitted through. It is also important to divide the system into physical components which have enough modes in the frequency band of interest at low frequency range. And it is useful way to apply the Power Flow Analysis using FEM to determination of main subsystems in the SEA model. Finally in order to improve the precision of the noise prediction, it is necessary to evaluate the average power flow between ship structural components and cabin interior components, to combine the SEA method and the Acoustic Radiation method.
