Abstract:
This paper identifies the different friction regimes encountered in elastohydrodynamic lubricated point contacts using a quantitative, physics-based approach. The idea is to link different traction regimes to dimensionless numbers and identify ranges of those numbers where a given regime is encountered or dominates the friction response of the contact. A numerical investigation of traction in point contacts lubricated with a typical mineral oil is employed. The measured thermo-physical properties of the oil are used without any modification to force agreement with experiments. The authors propose four friction regimes delimited by the combined values of three dimensionless parameters.
