摘　　要：以某高速重载数控5m立车的环形腔静压推力轴承为对象,对其润滑性能进行了研究,推导出静压承载力与油膜厚度的关系式。依据计算流体力学(CFD)理论,采用ANSYS ICEM CFD和ANSYS CFX软件对环形腔静压推力轴承内部流体压力场、温度场和速度场进行了仿真计算,通过改变油膜厚度实现对工作台承载变化的研究,得到了不同油膜厚度时压力场、温度场和速度场的变化规律,实现了高速重载静压推力轴承润滑性能预测。The lubrication performance for ring cavity hydrostatic thrust bearings of a high--speed heavy--duty 5m CNC vertical lathe was studied, the relationship between load capacity and film thickness was deduced. Based on CFD theory, using ANSYS ICEM CFD and ANSYS CFX, the pres- sure field, temperature field and velocity field of ring cavity hydrostatic bearing internal fluid were simulated. By changing film thickness the load changes of the worktable, changes of pressure field, temperature field and velocity field in different film thicknesses can be obtained. Thus, the lubrication performance prediction of high--speed heavy--duty hydrostatic thrust bearings will be realized.
