Numerical Analysis of Transient, Line-Contact Problems in Elastohydrodynamic Lubrication

Elastohydrodynamic (EHD) lubrication is a lubrication process which usually occurs in concentrated load-supporting or load-transmitting contacts. Such contacts exist, for example, in rolling-element bearings, gears and cam-follower mechanisms. In EHD lubrication, the contact surfaces are not only separated by a thin lubricating film, but also elastically deformed to an amount comparable to the film thickness. The film thickness in an EHD contact can be as small as a fraction of a micron, and the contact pressure can be as high as several GPa. Film thickness and pressure are closely related to surface failures such as scuffing and fatigue, and are therefore the most important considerations in EHD lubrication.
