Abstract
This paper shows the results of a comparison between theoretical models for predicting friction in point contacts under elastohydrodynamic lubrication and the experimental results obtained in a Mini Traction Machine (MTM). The types of models used are two variations of the Newtonian Theory, applicable to polyalphaolefins (PAO): the Limiting Shear Stress Model and the Carreau’s model. The experimental stage includes a wide variation of the operating conditions, by using different control parameters, such as temperature, contact materials, slide-roll ratio, sliding velocity and load.
