摘要
以多缆地球物理勘探船(以下简称物探船)为研究对象,分析了物探船主要的噪声源,包括主机、发电机组、螺旋桨工作产生的空气和结构噪声等。在满足MSC.337(91)《船上噪声等级规则》的舱室噪声标准限值要求基础上,采用商用船舶声学设计评估软件建立全船统计能量模型,对其进行舱室噪声预报,并针对结果提出可供参考的减振降噪设计建议,从而为提出声学设计和噪声控制重点奠定基础。
Cabin noise on multi cable geophysical prospecting ship was researched in this paper.Firstly,geophysical prospecting ship noise source,including host,generator set,propeller was analyzed.Secondly,based on statistical energy analysis theory,a numerical model was build to compute ship cabin noise.Then,the vibration noise reduction design suggestions,which laying a foundation for acoustic design and noise control were proposed.
