水线以上机电设备对船舶水下辐射噪声影响研究

摘要

This article established the acoustic finite element model of the SWAH, the vibration and noise of the diesel engine group as a source, calculated the underwater radiated noise of SWAH, made a preliminary research on the influence of above the waterline equipment on underwater radiated noise of SWAH, and provided a reference for underwater radiated noise of SWAH.%建立小水线面双体船声学有限元模型，以柴油发电机组振动噪声为激励，计算该船型水线以上振动噪声源产生的水下辐射噪声。探讨船舶水线以上振动噪声对其水下辐射噪声的影响规律，为整船水下辐射噪声评估提供参考。
