Abstract

In studies on lubrication analyses, researchers have investigated mixed lubrication as well as hydrodynamic lubrication. One of these published studies concerns lubrication analysis by considering not only the surface roughness but also the slope parameter of the friction surface; in the study, the relative slope of the pad bearing surface was confirmed to influence the friction characteristics. However, verification of whether the lubrication analysis values are comparable to those of the friction tests is yet to be conducted. In this study, to experimentally verify the results of this previous lubrication analysis, we developed an experimental device to derive the slope parameter and analyzed the results. The film thickness was calculated by analyzing the slope parameter obtained from the friction tests and was then used as the input value for lubrication analysis.


Keywords: Lubrication analysis, Friction test, Film thickness, Slope parameter, Mixed lubrication
