The influence of slide-to-roll ratio on lubricant film thickness distribution in the vicinity of real roughness features passing through EHD point contact

摘要

A combination of thin film colorimetric interferometry and phase shifting interferometry has been used to study the effect of slide-to-roll ratio on the micro-elastohydrodynamic action and asperity-contact mechanism on the real asperity scale. The purpose of this study is to provide some experimental data associated with the behavior of the roughness features of different scale in very thin film, real rough surface elastohydrodynamic contacts.
