摘要
水下辐射噪声的控制水平是现代科考测量船的重要指标,需要贯穿于整个船舶设计、建造和试验过程,尤其是初步设计阶段就需要将水下辐射噪声控制技术融入总体设计。文中重点分析了某测量船水下辐射噪声的振动噪声来源及传递路径,尤其是该船的GONDOLA附体结构以及安装于船体外的全回转推进器,给水下辐射噪声控制带来新问题、新困难。通过在设计、建造阶段采取螺旋桨优化设计、螺旋桨伴流优化设计、全回转推进器齿轮优化设计等控制措施,有针对性地控制水下辐射噪声,并在试航阶段对水下辐射噪声进行实船试验测试,试验结果满足挪威船级社SlientF(lightsurvey)的指标要求,为后续低水下辐射噪声调查测量船的设计、建造提供借鉴参考。
The control level of underwater radiation noise is an important index of modern scientific research survey ship,which needs to run through the whole process of ship design,construction and test,especially in the preliminary design stage,underwater radiation noise control technology needs to be integrated into the overall design.In this paper,the vibration and noise sources and transmission paths of underwater radiation noise of a survey ship are emphatically analyzed,especially the GONDOLA appendage structure of the ship and the full-rotary propeller installed outside the ship,which brings new problems and difficulties to the control of underwater radiation noise.The underwater radiation noise is controlled by taking control measures such as optimal design of propeller,optimal design of propeller wake and optimal design of full-slewing propeller gear in the design and construction stages.In the trial stage,the underwater radiation noise is tested on a real ship,and the test results meet the index requirements of Norwegian Classification Society Slient F(light survey),which can be used as a reference for the design and construction of subsequent low underwater radiation noise survey ships.
