摘要
Abstract
The acoustic characteristic of the ship wake is mainly determined by that of the bubbles in it. The acoustic characteristic of bubbles is behaved as the reflection and scattering of different frequency of sound waves, which is mainly up to the resonant frequency of the bubble. The modal aralyze method in the finite-element theory can be used to analyze the vibration of structure and obtain the intrinsic frequency of some structures in the result file. The application of the modal analysis on the model can prove the correction of the model, which can be used to study the acoustic characteristic of the ship wake.关键词
