The effects of surface roughness on the transient characteristics of hydrodynamic cylindrical bearings during startup
TL;DR: In this article, the effect of surface roughness on the transient characteristics of the hydrodynamic cylindrical bearing during startup is studied, and a mixed lubrication model considering both asperity contact and hydrodynamical fluid flow is solved.
Mixed-lubrication study of journal bearing conformal contacts
Qian Wang,Fanghui Shi,Si C. Lee +2 more
TL;DR: In this article, the average Reynolds equation derived by Patir and Cheng was utilized in the lubrication analysis of finite journal bearings operating with large eccentricity ratios to better understand the mixed lubrication phenomena in conformal contacts.

Numerical analysis on the dynamic contact behavior of hydrodynamic journal bearings during start-up
TL;DR: In this article, the authors investigated the dynamic contact behavior of hydrodynamic journal bearings during start-up by solving the mixed lubrication model and found that an increase in the relative clearance of the bearing generates a decrease in both the contact force and the contact time.

Determination of the transition speed in journal bearings under consideration of bearing deformation
T. Illner,Dirk Bartel,L. Deters +2 more
TL;DR: In this paper, the authors further developed an analytical model to calculate the minimum film thickness and the transition speed in journal bearings with consideration of bearing deformations, and compared the results of the new approach with previous analytical models and full numerical calculations.

A Theory of Mixed Lubrication
TL;DR: In this paper, the phenomena observed when a lubricated contact or bearing is operating under mixed lubrication conditions are assumed to arise from an interaction of the surface asperities or roughness as well as a...

A more general form of reynolds equation–Application to rough surfaces
D. Berthe,Maurice Godet +1 more
TL;DR: In this paper, it is shown that if one of the two moving contact surfaces is either rough or deformed and thus cannot be assimilated to a plane, Reynolds equation takes on a different form which is not equivalent to the classical equation.
