The Behavior of Surface Roughness in EHL Contacts Under Small Slide to Roll Ratios

Popis výsledku v původním jazyce

The amplitude attenuation theory represents a possible way how to predict the tribological performance of a surface having general roughness. There are applications of this theory for pure rolling and rolling?sliding conditions having different governingparameters. Obviously, pure rolling case is much simpler and it was already experimentally verified. Conversely, rolling?sliding conditions represent much complex case and its solution is still under development. Nevertheless, a lot of machine components operate under the conditions where only small slide to roll ratios are present. This study was carried out to find the reasonable validity of the pure rolling model for the applications where small amount of sliding is present. The behavior of roughness was observed under conditions of small sliding speed using optical tribometer for film thickness mapping. The results were analyzed and compared with the predictions according the amplitude attenuation theory for both pure rolling and r
