| Abstract: | Abnormal noise originates easily in bearings in the submarine propeller shaft applications during operation at low speed,which badly deteriorates the sound stealth of submarine.The key technologies of noise attenuation for submarine propeller bearing were deeply investigated for long at home and abroad.The many factors induce bearing noise,such as the bearing materials and structures,the surface status of bearing and propeller shaft,water temperature,the properties of water and so on.However,the researches ... |
