Abstract
A Brillouin scattering optical system using a Fabry-Perot interferomet er and a diamond-anvil cell was designed and set up for the evaluation of the mechanical properties of lubricants under high pressure in ela stohydrodynamic lubrication of ball bearings, gears and traction drive s. Brillouin scattering spectra for alcohols, hydrocarbons, and synthe tic lubricants were measured, and sound velocity and density under hig h pressure were obtained. The density was compared with Dowson and Hig ginson's density-pressure equation of lubricants, and density-pressure characteristics of paraffinic oils and naphthenic oils were described considering the molecular structure of solidified lubricants.
