摘要
指挥室围壳是潜艇水动力噪声最为突出的部位之一。为分析围壳水动力噪声的机理和特性,总结其控制技术特点和发展趋势。首先,对指挥室围壳水动力噪声的基本机理和组成进行概述,归纳梳理围壳直接辐射噪声、二次辐射噪声和开口流激空腔噪声这3类噪声源的国内外研究现状;然后,对围壳水动力噪声控制技术的研究进展进行概述,包括填角设计、"薄翼"型围壳设计、开口空腔噪声控制等;最后,针对围壳水动力噪声治理需要进一步研究的几个方面进行展望。通过系统地梳理总结,比较完整地阐述了围壳水动力噪声的基本机理和控制技术的进展概况,可供水动力噪声研究和舰船设计人员参考。
The sail is one of the most prominent contributors to the hydrodynamic noise of a submarine.This study seeks to analyze the mechanisms and characteristics of sail hydrodynamic noise,and summarize the characteristics and development trends of its control technology.First,the basic mechanisms and composition of sail hydrodynamic noise are summarized,as well as the research status of the direct radiation noise,secondary noise and cavity noise induced by flow-excitation of sails'opening.The research progress of sail noise control technology is then summarized,including fillet design,"thin foil"sail shape design,cavity noise control,etc.Finally,several aspects of further research on the control of sail hydrodynamic noise are proposed.This paper illustrates the basic mechanisms in the progress of sail hydrodynamic noise control technology.It can provide important reference value for researchers engaging in hydrodynamic noise and ship design.
