摘要
本文基于灰色系统理论,以5618箱集装箱船为母型船,利用灰关联分析法,分别确定了影响船舶上层建筑甲板平均噪声和各甲板舱室噪声的主要因素;采用非等间隔GM(1,1)建模的方法,分别建立上层建筑甲板平均噪声模型和各甲板舱室相对于甲板平均噪声的差值的模型,通过将两个模型的预测值求和来求得最终的上层建筑舱室噪声预测值。应用此模型对4100箱集装箱船上层建筑舱室噪声进行了预测,预测结果表明,用灰色预测方法对复杂的船舶上层建筑舱室的噪声进行预测是可行的,不仅能考虑多个因素的影响,而且具有样本少、预测快、精度较高等优点,尤其是在船舶开发设计的初期,较其它方法具有明显的优越性。
Based on the grey system theory, taking 5618TEU as the originated model and using grey relation analytical method, the main factors, which influence the deck average noise of the ship superstructure and the cabin noise of every deck, are determined in this paper. And then using the modeling method of non-equal interval GM(1,1), the deck average noise model of the ship superstructure and the noise difference model of the cabins relative to the deck average noise are established separately. By adding the prediction values of the two kinds of model, the final prediction values of the superstructure cabinsr noise are gained. These models are applied to predict the noise of 4100TEU's superstructure cabins, and the result shows that it is feasible to predict the noise of ship superstructure cabins using grey prediction method, which not only considers more factor influences, but also possesses some merits such as fewer stylebooks, quicker prediction, higher precision and so on. Especially in the initial period of the ship exploitation and design, this method gains obvious advantage over others.
