Deformation Behavior of Thin Lubricant Films at Elevated Pressure.

Abstract

The elastohydrodynamic (EHD) regime of lubrication is responsible for the generation of a protective film and the transfer of shear across concentrated contacts in many machine elements including bearings, cams and gears. It is now understood that small scale EFiD plays a major role in the boundary lubrication of rough surfaces. Many high pressure metal working operations share the pressure and kinematics of elastohydrodynamics. A complete solution of the EHD problem, however, requires a thorough knowledge of the lubricant constitutive behavior and the attending properties as flinctions of temperature and pressure. The Newtonian assumption alone is inadequate.
