The Study of Viscoelastic Properties of Lubricants Using High Pressure Optical Techniques

Recent investigations of EHD lubrication have indicated the importance of viscoelastic properties in explaining the differences in the behavior of different lubricants. Up to the present time, however, very little of the data necessary to develop a reliable viscoelastic model of EHD lubrication has been available. It is the purpose of this article to present a description of recently developed high pressure light scattering techniques which for the first time make an extensive study of the pressure and temperature dependence of the viscoelastic properties of lubricants feasible. Presented as an American Society of Lubrication Engineers paper at the ASLE/ASME Lubrication Conference held in Montreal, Canada, October 8–10, 1974
