Abstract : This report discusses the results of a series of pressure and temperature distributions measured between a pair of elastohydrodynamically (EHD) lubricated disks. Three lubricants have been studied: a synthetic paraffinic oil (XRM-109F), polyphenyl ether (OS-124), and a traction fluid (Santotrac 50). Pressure and temperature readings throughout the contact are presented as three-dimensional plots. Measurements of the EHD film thickness, and the tractive force between disks under slip conditions are also presented. A method for one-dimensional mapping of tractive force is introduced. An instrumental part of the method is the data handling capability of a digitizing oscilliscope which captures signals from the traction probe. The oscilliscope's capabilities are greatly expanded by a microprocessor which controls its functions. Preliminary results from this method of local traction measurement are presented. (Author)
