Parameter Identification of Hysteresis Friction for Coated Ball Bearings Based on Three-Dimensional FEM AnalysisSource: Journal of Tribology:;1997:;volume( 119 ):;issue: 003::page 462DOI: 10.1115/1.2833520Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Using a three-dimensional finite element model, the hysteresis friction behavior of coated ball bearings is investigated. Ninety-six distinct operating conditions were examined by the finite element model that include normal loads of 81.6, 133.5, and 185.4 N per ball, ball diameters of .0127 m and .0191 m, ball materials of Si3 N4 and steel, substrate materials of Si3 N4 and steel, and coating materials of MoS2 , NbSe2 , Si3 N4 , and steel. From the finite element results, general trends for the two parameters of Dahl’s friction model, the rest slope, σ, and the steady friction torque, Ts , are established for coated surfaces. By performing a regression analysis of the data points, empirical expressions for σ and Ts are derived for coated bearing surfaces. These expressions are authenticated by comparisons to laboratory experimental results.
