Abstract
A comprehensive set of experiments incorporating some of the significant factors affecting wear under mixed lubrication of journal bearings has been carried out following Taguchi's technique. Using carburized plain carbon steel like-pair bearing materials, wear characteristics and surface topography changes have been studied. Statistical analysis of mean and variance of test results reveals that, among the different factors considered, frequency of starts and stops, journal surface velocity, load and hardness influence the specific wear rate of the bush to a large extent. Hydrodynamic and asperity load computations correlate well with the experimental results. In addition, surface topography changes occurring during the wear process, related to power spectral density and fractal dimension, yield quantitative information regarding characterization of the wear process. © 1994.
