RISSurface Roughness Effects in an EHL Line Contact
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper the influence of surface roughness on the pressure profile and film thickness in a steady state EHL line contact is investigated using input from an actually measured roughness ...

Sinusoidal Three-Lobe Bearings—Optimization and Stability Charts
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In contradistinction to the commonly used segmented three-lobe bearing, another type of bearing, i.e., the sinusoidal three-lobe bearing has been investigated in this paper. The main advantage ...
The Influence of Elastic Deformation of the Roll and the Sheet in a Hydrodynamically Lubricated Cold Rolling Process
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A model has been developed for simulating hydrodynamic lubrication in cold rolling. Both Roelands’ and Barus’ viscosity-pressure relations have been applied. Thermal effects regarding heat development ...
The Influence of Longitudinal and Transverse Roughness on the Elastohydrodynamic Lubrication of Circular Contacts
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The effect of longitudinal and transverse roughness on the elastohydrodynamic lubrication of circular contacts was investigated numerically for two different lubricating conditions. The influence ...
Multigrid, an Alternative Method of Solution for Two-Dimensional Elastohydrodynamically Lubricated Point Contact Calculations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Detailed and accurate film thickness and pressure profiles have been calculated for point contacts at moderate and high loads, using a multigrid method. The influence of the compressibility of ...

Dynamically Loaded Pivoted Pad Journal Bearings: Mobility Method of Solution
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The mobility-whirl angle method as introduced by Booker in 1964, has been applied to pivoted pad journal bearings to predict the behavior of a rotor supported in this type of bearing. Both ...
Multigrid, An Alternative Method for Calculating Film Thickness and Pressure Profiles in Elastohydrodynamically Lubricated Line Contacts
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Film thickness and pressure profiles have been calculated for line contacts at moderate and high loads, using a Multigrid method. Influence of the compressibility of the lubricant on the minimum ...
Numerical Simulation of the Overrolling of a Surface Feature in an EHL Line Contact
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper a Multigrid extension of a stationary solver is outlined for the EHL solution of a line contact under transient conditions. The solver is applied to calculate pressure and film ...
