| 摘 要： | 以粤海铁路火车渡轮作为研究对象,利用统计能量法—VA one软件建立了声学计算模型,舱室噪声初步评估结果表明:部分舱室噪声超标。通过一定的减振降噪措施后,对舱室噪声进行再评估,并与实测值比较,两者接近。说明该方法可以用于舱室噪声预报,对船体初期设计具有一定的参考价值。

| Abstract: | Taking Guangdong-Hainan railway train ferryboat as the research object,the acoustic calculation model was built by the statistics energy analysis tools-VA one software.The primary cabins noise assessment results showed that some of the cabins noises go beyond the criteria values.The cabin noises were reassessed after some vibration isolations and noise treatments,and compared with the measured data on board,the two group of data were similar,which means this method could be used as cabin noise prediction and is valuable in earlier hull design. |
