| 摘 要： | 本文以某化学品油船为目标船舶,利用VA One软件建立其统计能量分析模型并预报其舱室噪声,随后对模型进行了某些简化,研究了液舱内的液体介质和双层底结构的改变对舱室噪声预报的影响.研究结果表明液舱内的液体介质和双层底的具体结构形式对于舱室的噪声影响很小,可以不予考虑,今后在建立船舶的统计能量分析模型时,可以将双层底简化为一个大的声腔,从而减少建模工作量,提高效率.

| Abstract: | Taking a chemical tanker as target ship, the article uses VA One software to establish its statistical energy analysis model and predict its cabin noise. And then we simplify the model to study the influence on the noise prediction of ship cabin when liquid medium and double bottom structure are changed. The results indict that both factors have little influence on ship noise,even can be ignored. So, in futureresearch, when we establish the statistical energy analysis model of the ship, the double bottom can be simplified as a large cavity to reduce the modeling workload and improve the efficiency. |
