A Study on the Lubrication effects of surface roughness

The influence of one sided striated surface roughness on load carrying capacity of a slider bearing is analyzed for very low clearance films. A Reynolds equation appropriate for slider bearing is derived and analyzed by the method of finite difference method. For a slider bearing with several simple roughness form, the pressure, load capacity and other parameters can be revealed and also this results can be stored in sequential data file. After all, their distribution can be displayed easily by using the CADG(Computer Aided Design and Graphics) program. Also exact solutions with this nemerical method are compared with those of the theory attributed to Tonder and White. The results reported here should find application in the computer peripherals where computer aided design and graphic package is needed.
