摘　　要：为准确预报螺旋桨的空泡性能和脉动压力性能,以某科考船螺旋桨为研究对象,分别在空泡水筒和减压水池进行空泡和脉动压力模型试验。对荷兰MARIN减压水池的试验方案进行论述,并对比分析空泡水筒和减压水池的试验结果。试验结果表明:目标船螺旋桨的空泡性能优秀,在11 kn航速工况下,螺旋桨无任何型式的空泡出现;在11 kn和15 kn航速工况下,螺旋桨的脉动压力非常小,该船的螺旋桨不会引起振动问题。螺旋桨应能满足挪威船级社DNV-GL Silent-R的低噪声要求。In order to predict the characteristics of cavitation and fluctuating pressure of marine propeller precisely, taking the propellers of a scientific research vessel as object, the cavitation observations and fluctuating pressure measurements are carried out both in depressurized towing tank and cavitation tunnel. The test scheme in depressurized towing tank of MARIN is studied, and the test results in two facilities are analyzed.According to the model test results, the cavitation performance is excellent, and propeller will be cavitation free at ship speed of 11 kn. The level of propeller-induced fluctuating pressure is very low at the speed of 11 kn and 15 kn, and no ship vibration is expected. The propeller can meet the low-noise requirements of DNV-GL Silent-R.
