Based on the average flow equation and the Ng-Pan turbulence model, using the boundary condition of mass conserving (JFO), a mixed lubrication model considering wear and turbulence was established. A finite difference method was used to solve the model. Under the condition of constant external load, the effects of wear and turbulence on oil film pressure, oil film thickness and friction coefficient were studied. The results show that wear significantly changes the oil film pressure and oil film thickness distribution, and has an important influence on the Stribeck curve of bearing. Under high-speed operating condition, turbulence reduces the maximum oil film pressure of the bearing, and increases the minimum oil film thickness, cavitation zone, and friction coefficient. Wear and turbulence have a critical impact on the lubrication performance of the bearing, and the two together determine the lubrication performance of the bearing.
