Transient mixed thermo-elastohydrodynamic lubrication in multi-speed transmissions [PDF]

open access: yes, 2012
Noise, vibration and harshness (NVH) refinement as well as thermo-mechanical efficiency are the key design attributes of modern compact multi-speed transmissions.

Piston Compression Ring Elastodynamics and Ring–Liner Elastohydrodynamic Lubrication Correlation Analysis

open access: yesLubricants, 2022
Friction loss in an internal combustion engine largely depends on elastohydrodynamic lubrication. The piston compression ring is a contributor to such parasitic losses in the piston subsystem.

A review of some tribo-dynamics phenomena from micro- to nano-scale conjunctions [PDF]

open access: yes, 2009
The paper provides some highlights in the developments of theories of lubrication and contact mechanics from early pioneering works of Reynolds and Hertz to the establishment of elastohydrodynamic phenomenon by Ertel and Grubin. Some historical discourse

Investigation of Couple Stress Fluid and Surface Roughness Effects in the Elastohydrodynamic Lubrication Problems using Wavelet-Based Decoupled Method

open access: yesLubricants, 2016
The standard decoupled method with Newton-generalized minimum residual procedure performs poorly or may break down when used to solve certain elastohydrodynamic lubrication problems.

Wavelet based decoupled method for the investigation of surface roughness effects in elastohydrodynamic lubrication problems using couple stress fluid

open access: yesAin Shams Engineering Journal, 2018
In this paper, we developed the wavelet based decoupled method for the numerical solution of elastohydrodynamic lubrication problems. The standard decoupled method with Newton-generalized minimum residual procedure performs poorly or may break down when ...

Comment on Neupert, T.; Bartel, D. Evaluation of Various Shear-Thinning Models for Squalane Using Traction Measurements, TEHD and NEMD Simulations. Lubricants 2023, 11, 178

open access: yesLubricants, 2023
The field of EHL (elastohydrodynamic lubrication) may be the only one in science in which a model for shear-dependent viscosity would be evaluated by means other than viscometer measurements [...]

Mutual influence of cross hatch angle and superficial roughness of honed surfaces on friction in ring-pack tribo-system [PDF]

open access: yes, 2013
The cylinder bore surface texture, widely produced by the honing technique, is an essential factor for a good engine performance (friction, oil consumption, running-in, wear etc.).

Cavitation induced starvation for piston-ring/liner tribological conjunction [PDF]

open access: yes, 2011
The study investigates the mechanism of ring-liner lubrication in the vicinity of the top and bottom dead centres of an internal combustion engine. Predicting lubricant transient behaviour is critical when the inlet reversal leads to thin films and ...

Monitoring the lubricant condition in a low-speed rolling element bearing using high frequency stress waves [PDF]

open access: yes, 2002
This paper presents the results of an investigation into the development of a reliable, nonintrusive and effective technique capable of accessing the lubrication condition within a low-speed rotating bearing.
