Modern machine elements are required to work under increasingly severe conditions
(thinner lubricating films, higher temperatures, less lubricant, etc.). Therefore, in heavily …

The ability of elastohydrodynamically lubricated (EHL) contacts to separate surfaces
represents essential design requirement ensuring long life and low friction of machine …

This article is focused on the effects of the angle between lubricant entrainment velocity and
sliding velocity on elastohydrodynamic film thickness distribution. Thin-film colorimetric …

The commonly accepted “roughness attenuation” theory offers a description of the
deformation of surface features as they travel through elastohydrodynamic lubricated …

Using a custom-made optical interferometer, the waviness values on the raceway of the
washer of two thrust ball bearings are obtained by applying the Hertzian contact theory. The …

Film thickness prediction plays an important role in evaluating the performance and
durability of machine elements under elastohydrodynamic lubrication (EHL). However …

This article presents experimental results of artificial roughness behavior inside
elastohydrodynamic contacts. An optical tribometer with a high-speed camera was used to …

The film thickness profile obtained by the optical interferometry technique merely represents
a separation between contact surfaces and does not give the surface shape of contact …

Machine components are designed to endure increasingly severe operating conditions due
to the strive for improved energy efficiency of mechanical systems. Consequently, lubricated …

This work investigates the transient effects of a single subsurface inclusion over the
pressure, film thickness, and von Mises stress in a line elastohydrodynamic lubrication …
