摘　　要：试航中发现某型油船主机在450～600r/min时,在螺旋桨的正上方能明显听到异常噪声。通过定性分析排除了螺旋桨上有缠绕物、轴系的配合问题,定量分析排除了螺旋桨出现“谐鸣”的可能性,实船测试分析结果表明产生噪声的原因是由于螺旋桨出现了梢涡空泡现象。研究为船舶的同类现象提供参考。In the trial voyage of a type of oil tank, abnormal noise was detected above the propeller, which made people bored and worried. Quantitative analysis precluded the possibilities of something wraped on the propeller and the shaft assembly. Qualitative analysis precluded the possibility of harmonic ringing. The analysis result of the measurement shows that the main reason for the noise is cavitatain around the propeller blades. The paper has good refer value for the some kind phenomena of ships。
