EXPERIMENTAL STUDY OF ELASTOHYDRODYNAMIC LUBRICATION,

Abstract

The report describes direct experimental measurements of pressure distribution, surface temperature and film shape or deformation profile which were obtained during an investigation of elastohydrodynamic lubrication. These measurements illustrate effects of load, rolling speed, lubricant properties and sliding speed. Their purpose is to provide guidance and verification for the development of an elastohydrodynamic theory which can then be generally applied to practical problems in the manner which has been described. The results agree with the thermal-elastohydrodynamic theory of Cheng in many respects, but there are also differences which indicate that certain modifications in the formulation of the theory should be made.
