Abstract
A SEMI-EMPERICAL APPROACH TO MODELING THE TRACTION BEHAVIOR OF LUBRICANTS IN CONCENTRATED CONTACTS IS PROPOSED. THE MODELING CONSISTS OF POSTULATING THE FORM OF THE LUBRICANT CONSTITUTIVE EQUATION IN THE HIGH-PRESSURE CONTACT ZONE AND ESTIMATING THE VARIOUS COEFFICIENTS BY CARRYING OUT A NONLINEAR LEAST SQUARES ANALYSIS OF THE AVAILABLE TRACTION DATA. THE EFFECTIVENESS OF THE MODELING APPROACH IS DEMONSTRATED BY INCORPORATING THE LUBRICANT TRACTION MODEL IN A BEARING DYNAMICS COMPUTER CODE AND BY CARRYING OUT BEARING PERFORMANCE SIMULATIONS AS A FUNCTION OF THE COEFFICIENTS OF THE TRACTION MODEL.
