基于SEA的海洋平台典型舱室噪声预报及设备优化布置研究

摘要

Based on the Statistical Energy Analysis, this paper predicts the cabin noise of the typical cabin structure of the offshore platform under the air noise effect of the split air-conditioning outdoor unit with VA ONE software. Under the premise of the given structure size and the magnitude of load, this paper changes the air outlet orientation of the split air-conditioning outdoor unit, compares and analyzes the cabin noise. It concludes that the air outlet orientation has a great influence on cabin noise, which provides the certain reference for the cabin noise prediction and the equipment layout in Naval Architecture and Marine Engineering.%基于统计能量法，利用VAONE软件对海洋平台典型舱室结构在分体空调室外机空气噪声作用下的舱室噪声进行预报。在保证结构尺寸与载荷大小的前提下，改变分体空调室外机出风口朝向、对比分析舱室噪声，得出分体空调室外机出风口朝向会对舱室噪声产生较大影响。该研究对船舶与海洋工程舱室噪声预报及设备布置方面具有一定的参考价值。
