Influence of Micro-morphology on Thermal Elatohydrodynamic Lubrication of Water-lubricated Tenmat Bearing
The elastohydrodynamic lubrication numerical analysis of water-lubricated tenmat bearing with single sine-type peak,single V-type valley and single rectangular-type valley was carried out by using the Reynolds equation.The results show that,for the bearing with single peak,the partial pressure peak appears and the corresponding film thickness increases rapidly and then decreases; With the increase of the amplitude of the sine function,the partial pressure of the lubricating film is also increased,the partial film thickness is decreased,as the wavelength increases,the pressure and the film thickness of the convex portion widened,the peak remains substantially unchanged.For the bearing with single V-type valley and single rectangular-type valley,the partial pressure are decreased,the partial film thickness are increased; with the amplitude of the roughness function increases,the partial pressure are decreased,on the contrary,the partial film thickness are increased; with the wavelength increases,the pressure and the film thickness of the convex portion widened.
