The Pressure and Deformation Profiles Between Two Normally Approaching Lubricated Cylinders
K. M. Lee,H. S. Cheng +1 more
TL;DR: In this paper, the authors obtained the pressure and deformation profiles between two colliding cylinders by solving the coupled, time-dependent elastohydrodynamic equations with an iterative procedure.
Journal ArticleDOI
The effect of surface roughness on the average film thickness between lubricated rollers
L. S. H. Chow,H. S. Cheng +1 more
TL;DR: In this paper, the effect of surface roughness on elastohydrodynamic contact between two rollers is investigated. But the results of these two cases show that the effects are similar to those found in elasthydrodynamic contacts.
