| 摘 要： | 以某万吨级油船为目标船，介绍了油船典型舱室噪声分析预报声学有限元（FE）、统计能量（SEA）数值分析理论和方法．并根据IMO规范对所关注舱室的噪声水平进行评价，针对超标的舱室给出减振降噪处理方案。计算考虑了船舶桨、主机、空调及风机等噪声源引起的结构噪声和空气噪声。

| Abstract: | Taking a ten-thousands-ton oil tanker as target model,this paper introduces FE and SEA analysis methods to predict the typical cabin noise,evaluates its noise level by IMO rule,and provides methods to attenuate the vibration and noise of the noise excessive cabins.The structure borne noise due to propeller excitation source,and airborne noise due to diesel,fans,air-conditions and other auxiliary machines are both considered. |
