Abstract: With a 12-cable geophysical vessel as an example, the underwater noise evaluation technology of ships were studied by means of the combination of the FEM and BEM according to the frequency band features of the vessel. The evaluation methods were verified. Some measures for noise control of ships were proposed and verified by a real-ship testing. The evaluation methods of underwater noise and measures for noise control proposed in this work provide a reference for underwater noise control of the deep-water geophisical vessels.
Key words: acoustics, geophysical vessel, underwater noise evaluation, FEM, BEM
摘要: 以12缆深水物探船为研究对象,根据该船主要物探频段特点,采用有限元和边界元相结合的方法进行船舶水下噪声评估技术研究,对评估方法进行验证;提出船舶噪声控制措施,通过实船测试,满足设计要求。物探船水下噪声评估方法及控制措施可为我国自研深水物探船水下噪声控制作参考。
