Mixed lubrication — an overview

Lubrication Science, 1997
AbstractThe regime known as ‘mixed’ lubrication lies between those of hydrodynamic and elastohydrodynamic. This paper reviews work on this subject, in order to recognise the key areas of progress, and of ignorance. Film thickness and surface roughness are discussed, to conclude that below certain values of λ, there are limitations to earlier models ...

Coupling transient mixed lubrication and wear for journal bearing modeling

Tribology International, 2019
A transient Mixed Lubrication-Wear coupling model (MLW coupling model) is developed to investigate the mixed lubrication and wear performances of journal bearings, and a wear experiment for journal bearing is performed to support the validity of the ...

Mixed-lubrication analysis of planetary roller screw

Tribology International, 2019
The mixed-lubrication model of the planetary roller screw is proposed considering contact load, contact geometry of thread, surface roughness and transient effects.

A thermo-elastohydrodynamic lubrication model for hydraulic rod O-ring seals under mixed lubrication conditions

Tribology International, 2019
Because of the fluid viscous shear and the asperity contact friction, a temperature rise will occur in the sealing zone, which may cause rupturing of lubrication films or wear failure of seal rings.

Machine learning approach for the prediction of mixed lubrication parameters for different surface topographies of non-conformal rough contacts

Industrial Lubrication and Tribology, 2023
Purpose This study aims to use a machine learning (ML) model for the prediction of traction coefficient and asperity load ratio for different surface topographies of non-conformal rough contacts.
