舰船通海管路低频消声技术的研究进展

摘要

The application environment of hydrodynamic and low frequency noise attenuation techniques in naval vessel is analyzed at first in this paper, which points out the characteristics of sound propagation and excitation, requirements of safety and size in sea water piping system. Then, hydrodynamic and low frequency noise attenuation techniques, including traditional reactive silencer, gasbag silencer, elastic plate silencer and ANC, are analyzed in detail. The advantage and disadvantage of all kinds of these techniques is presented in this paper, which indicates the work to be carried out in the future.%分析水管路低频消声技术的实船应用环境，指出通海管路在声传播、空间布置等方面存在的特点以及安全性、空间布置等方面的要求。在此基础上，将通海管路低频消声技术分为传统抗性消声技术、气囊式消声技术、水动力弹性板式消声技术以及主动消声技术等4个方面，结合实船环境，详细分析各项技术的优缺点，指出下一步应继续开展的工作。
