Research on Elastohydrodynamic Lubrication of High Speed Rolling-Sliding Contacts

Abstract

A rolling disc apparatus was used to obtain traction measurements for a MIL-L-7808 oil. A full matrix of data covering a range of loads, speeds, and temperatures are presented along with analytical correlation which reasonably describes the data over these parameters. Attempts were made to measure film thickness with optical, capacitance, and X-ray measuring techniques. The partial elastohydrodynamic regime was studied analytically and experimentally. Electrical continuity and resistance data have been obtained and comparisons between measured electrical resistance and predictions obtained with the asperity interactions analysis put forth in Task 2 were obtained.
