基于平均流量方程和Ng-Pan紊流模型，采用质量守恒边界条件（JFO），建立了考虑磨损和紊流的混合润滑模型，使用有限差分法对模型求解。在外载荷恒定的条件下，研究紊流和磨损对轴承油膜压力，油膜厚度和摩擦力的影响。结果表明：磨损显著改变了油膜压力和油膜厚度分布，并对轴承Stribeck曲线有重要的影响。在高转速工况下，紊流使得轴承最大油膜压力减小，最小油膜厚度、空化区和摩擦系数增大。磨损和紊流对轴承润滑性能均有重大影响，二者共同作用决定轴承的润滑性能。

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.
