A thorough understanding of the mechanisms of micro contactlubrication and failure is required in order to optimize machinecomponent design for extreme operating conditions. In the verylow λ ratio, the ratio of lubricant filmthickness to surface roughness, asperity contacts play animportant role. Analysis of lubrication and failure of microcontact should include details of surface topography and itscharacterization, asperity contact pressure, micro lubricationpressure and film shape, as well as micro contact temperature.These aspects are discussed in this paper and typical numericalresults are given. Modeling and simulation tools are availableto describe the solid contact of asperity tips and the collapseof the lubricant film. It appears possible to investigate thetransition from full EHL to boundary lubrication by using themodel developed. [ABSTRACT FROM AUTHOR] |
