船用螺旋桨噪声研究进展

Research Development of Marine Propeller Noise

船用螺旋桨位于船舶最末端,既是驱使船舶前进的一个重要部件,又是船舶航行中引起噪声问题的一个主要因素。文章概述了螺旋桨空泡噪声、螺旋桨无空泡噪声和螺旋桨鸣音产生的原理,详细介绍目前国内外对这3种螺旋桨噪声的研究现状,分析并归纳研究螺旋桨噪声采用的方法,指出未来研究船用螺旋桨噪声的方向。

Marine propeller is located at the very end of the ship. It is not only an important part to drive the ship, but also a main factor causing the noise problem in the ship navigation. The principle of propeller cavitation noise, propeller non-cavitation noise and propeller singing are summarized in this paper. This paper introduces the research status of these three kinds of propeller noise at home and abroad in detail, analyzes and summarizes the methods used to study the propeller noise, and points out the future research direction of marine propeller noise.
