摘要：The modified Reynolds equation is established on the basis of critical shear stress model, in which the circumferential and axial wall slip of sleeve and journal surface is considered. Cavitation is treated using modified Elrod algorithm that simplifies the solution of modified Reynolds equation in the full-film region. The modified Reynolds equations considering wall slip and cavitation effect for two-dimensional sleeve bearing are established. The results show that wall slip decreases oil film pressure, carrying capacity, friction drag and temperature rise but increases end leakage and cavitation region. The obtained results using the mass-conserving boundary condition are compared with the Reynolds boundary condition. Copyright (c) 2014 John Wiley & Sons, Ltd.
