EHL oil film thickness under rolling-sliding contact
Journal of Mechanical Engineering, 1970 The Elastohydrodynamic lubrication (EHL) minimum oil film thickness is theoretically investigated under rolling with sliding contact. The effects of contact pressure, rolling speed and slip ratio on the EHL minimum oil film thickness are calculated numerically.

Spreading Behavior of Single Oil Droplet Impacting Surface with/without a Thin Liquid Film
Lubricants, 2023 When oil droplets impact a solid surface for oil-air lubrication, they may spread out to produce a thin oil layer on the surface, which serves as a significant source of lubrication.

Advanced Engineering Materials, EarlyView.The tribological behavior of 100Cr6 steel spheres textured via Vickers microindentation is evaluated under lubricated sliding by varying both dimple size and density. Fine and dense textures significantly reduce friction across all lubrication regimes, while large dimples increase it.

An ultrasonic measurement method for full range of oil film thickness
Proceedings of the Institution of mechanical engineers. Part J, journal of engineering tribology, 2018 Ultrasonic method is quite promising for oil film thickness measurement in industry, while there is normally a dead zone for one ultrasonic sensor with a special center frequency when measuring the oil film thickness by the traditional reflection ...
