高速船舶的螺旋浆噪声

THE VIBRATION OF PROPELLER ON HIGH SPEED SHIPS

本文描述高速船舶的振动源及噪声源,并介绍某些模型的实验结果,按照窄带频谱分析区分不同的振动源与噪声源,最后给出一些与理论分析一致的重要结论作为改进船舶设计的参考。

This paper discribes the main sources of vibration and noise of high speed ships, it also intoduces some experimental results from some models. According to the narrow band frequency spectrum analysis from which we can identify the sources of vibration and noise. We have given some conclusions which are coincident with theoretical analysis and important for the improvement of ship's design.
