Elastohydrodynamic lubrication calculations used as a tool to study scuffing [PDF]
A new Reynolds equation was developed that takes into account the nonlinear viscous behavior of the fluid. The new Reynolds equation considers the nonlinear viscous fluid model of Eyring, the equilibrium equation, the constant mass flow, and the ...

The practical impact of elastohydrodynamic lubrication [PDF]
The use of elastohydrodynamics in the analysis of rolling element bearings is discussed. Relationships for minimum film thickness and tractive force were incorporated into computer codes and used for bearing performance prediction.

Elastohydrodynamic contacts. Effects of dents and grooves on traction and local film thickness [PDF]
Traction and film thickness were simultaneously measured under sliding elastohydrodynamic (EHD) conditions. The influence of surface topography was investigated by using simulated surfaces produced by depressing dents and grooves in highly polished steel

Thermal elastohydrodynamic lubrication of spur gears [PDF]
An analysis and computer program called TELSGE were developed to predict the variations of dynamic load, surface temperature, and lubricant film thickness along the contacting path during the engagement of a pair of involute spur gears.
