A fast, robust, straightforward algorithm for thermal elastohydrodynamic lubrication

Tribology International, 1993
Abstract A straightforward computational algorithm is developed for solving thermal elastohydrodynamic lubrication problems in concentrated rolling/sliding line contacts. The algorithm is more efficient for pressure calculation than the conventional Newton-Raphson algorithm, can be used in both micro thermal and non-Newtonian thermal ...

Thermal Elastohydrodynamic Lubrication of Rough Surfaces

Journal of Tribology, 1990
A numerical solution to the problem of thermal and compressible elastohydrodynamic (EHD) lubrication of rolling/sliding rough surfaces was obtained by neglecting the transient effects. The technique involves the simultaneous solution of thermal Reynolds and modified elasticity equations using the Newton-Raphson technique, and the energy equation using ...

Thermal Elastohydrodynamic Lubrication of Axially Crowned Rollers

Journal of Tribology, 2021
Abstract This work presents a comprehensive numerical study of thermal elastohydrodynamic lubrication performance in axially crowned rollers, based on a full-system finite element approach. Axial crowning has always been introduced to finite line contacts, as a mean for improving film thickness.

Formulas Used in Thermal Elastohydrodynamic Lubrication

Tribology Transactions, 1991
A numerical solution to the problem of thermal compressible elastohydrodynamic lubrication of rolling/sliding contacts has been tested over a wide range of operating parameters consisting of dimensionless load, speed, slip, and material parameters. A least squares exponential curve fit was used to develop simple formulas for the amplitude and location ...

Non-Newtonian Thermal Elastohydrodynamic Lubrication

Journal of Tribology, 1991
A numerical solution to the problem of thermal and non-Newtonian fluid model in elastohydrodynamic lubrication is presented. The generalized Reynolds equation was modified by the Eyring rheology model to incorporate the non-Newtonian effects of the fluid.
