Elastohydrodynamic lubrication in point contact on the surfaces of particle-reinforced composite
AIP Advances, 2018 Appreciable friction and serious wear are common challenges in the operation of advanced manufacturing equipment, and friction pairs may be susceptible to damage even with oil lubrication when point contact exists.

An NURBS-based isogeometric analysis model for soft EHL contacts
FrictionThis paper presents a non-uniform rational B-splines (NURBS)-based isogeometric analysis (IGA) framework for modeling both hard and soft elastohydrodynamic lubrication (EHL) contacts under the fully flooded condition.

The Influences of Surface Texture Topography and Orientation on Point-Contact Mixed Lubrication
LubricantsSurface topography plays a critical role in determining the tribological performance of engineering surfaces. This study systematically investigates the lubrication film characteristics of bump array surfaces (isotropic and anisotropic), groove surfaces,

The viscosity at the glass transition of a liquid lubricant
Friction, 2018 In the classical study of elastohydrodynamic lubrication (EHL) which does not employ real, measurable viscosity in analysis, the possibility of a glass transition has not been considered in many years. Indeed, the two rheological assumptions of classical

LubricantsThis study tests TiO2 and SiO2 nanolubricants in PAG oil using a Mini Traction Machine and an Ultra Shear Viscometer. The loads were 20 N and 40 N. The entrainment speeds ranged from 2.5 to 500 mm/s. The slide-to-roll ratio (SRR) ranged from 25 to 150%. The nanoparticle concentrations were 0.01, 0.03, and 0.05%. The ball size was 19.05 mm, and the disc

Lubricants, 2015 Many studies have already considered starved lubrication. However, there have been no reports on the oil film thicknesses under steady starved EHL (elastohydrodynamic lubrication), where the ultra-low volume of oil supplied per unit time is uniform.

Advances in Materials Science and Engineering, 2020 A numerical solution for line contact elastohydrodynamic lubrication (EHL) occurring on the rough surface of heterogeneous materials with a group of particles is presented in this study. The film thickness disturbance caused by particles and roughness is
