摘要
The effects of anisotropic slip on the lubrication performances of journal bearings are analyzed. The anisotropic slip boundary conditions on bearing surfaces or/and on journal surfaces are modeled from Navier slip boundary condition with orthogonal principal slip lengths. The modified Reynolds equation considering anisotropic slip is then derived and solved numerically by the finite element method. The effects of principal slip lengths on the load capacities and friction force of journal bearings are discussed. The related Couette and Poiseuille flow correctors in the modified Reynolds equation and in the shear stress are presented to assist our discussion. (C) 2013 Elsevier Ltd. All rights reserved.
