基于统计能量法的海洋平台舱室噪声预报及控制

摘要

舱室噪声预报和控制对于提高船舶安全性和船员舒适性具有重要意义.本文基于统计能量法,根据CCS相关要求,采用VAONE软件对某新型海洋平台进行舱室噪声预报及控制研究,分别对4种不同内损耗因子进行讨论,通过分析超标舱室的噪声来源,采取有效的控制手段,为此平台的降噪设计提供参考依据,具有工程实用价值.%The prediction and control of cabin's noise are of great importance for the safety and comfort of the ships. Based on statistical energy analysis (SEA), the cabin′s noise of offshore platform is predicted by VAONE software accord-ing to the rules of CCS. In the process of discussing the numerical results, four different kinds of damping loss factor (DLFs) are considered. The effective measures are used to control the noise by analyzing the noise source of the over-standard cabin. The related results and conclusions are quite helpful for the design of offshore platform for reducing the noise and have great significance in practical engineering applications.
