摘要
应用统计能量法利用VA One软件对18万t散货船全船舱室噪声水平进行预报,选择典型舱室作为研究对象,将预报值与母型船实测值、规范限值对比,发现大部分舱室的噪声预报值满足规范要求,与实船测量值误差范围在3 dB(A)以内,医务室的预报值超出规范要求2. 6 dB(A),提出修改方案。
The statistics energy analysis method was applied to predict cavities noise level of a 180 000 DWT bulk carrier.The noise predicted results of the typical cavities were compared with the test values of the original vessel and the criterion values,showing that noise predicted values of a majority of cavities meet the specification request,and the measured error range is below 3 dB(A). As the noise predicted value of hospital,which is taken as accommodation cabin,exceeds specification requirement 2. 6 dB(A),a properly modification scheme was set forth to lower the noise level of hospital.
