A new efficient flow continuity lubrication model for the piston ring-pack with consideration of oil storage of the cross-hatched texture

TL;DR: In this article, a new efficient flow continuity lubrication model for the piston ring -pack is established by taking the oil storage of the cross-hatched texture into account, and the trapped oil in the texture is calculated as an extra oil supply to the inlet of the contact.

The Scale Effect of Roughness on Hydrodynamic Contact Friction

TL;DR: In this article, a numerical model of elastohydrodynamic contact coupled with a multiscale surface texture model was developed that allows tracking the scale effect of surface features and their interactions on friction performance and lubricant flow under hydrodynamic lubrication conditions.

Stress analysis of elastic coated solids in point contact

TL;DR: In this article, a point contact model of a rigid ball and an elastic coated solid is presented by combining the traditional contact model and the influence coefficients (ICs), which are obtained from frequency response functions with a conversion method based on FFT.

Mild wear maps for boundary lubricated contacts

TL;DR: In this paper, a model capable of predicting a mild wear map for boundary lubricated contacts is presented and validated using model experiments, which is based on the hypothesis that for an additive to protect the surface against severe wear a sacrificial chemical layer should be present at the surface.
