摘　　要：结合试验实测数据对船舶低速航行时出现附加噪声的现象进行了分析,论述了轴系回旋运动加剧艉部密封结构摩擦引发附加噪声的发声机理。并据此对船舶推进系统的低噪声运行和设计提出几点建议。According to the result of ship noise measurement, the source causing ship radiating add-noise was analysed. The friction of stern seal structure caused by shaft circumnutation may be the reason causing this add-noise. Based on this point some advices about how to design low noise ship propulsion system and how to control this kind of noise were proposed.
