摘　　要：针对圆锥液体静压轴承油膜发热的问题,采用积分法推导了绝热条件下圆锥液体静压轴承的平均温升公式,并利用ANSYS CFX软件,对圆锥液体静压轴承的流场和温度场进行了仿真分析。公式计算结果和仿真计算结果吻合良好,通过仿真获得了锥形油膜各点的温度分布。结果表明,转速对油膜温升和温度场分布有一定影响,油膜两端的温升差异较大。对圆锥液体静压轴承的结构设计和工艺参数优化有一定的的参考意义。According to the problem of temperature rising of conical hydrostatic bearing, the average temperature rising formula is derived by integral method under the adiabatic postulate here. Then a simulation analysis on the conical hydrostatic bearing is carried on to obtain the flow field and the temperature field of the conical oil film by using ANSYS CFX. The simulation result corresponds to the theoretical calculation quite well. The simulation result reveals the temperature distribution of the conical oil film. The results show that the temperature rising and distribution is related to the rotational speed. The temperature of the oil film＇s two ends are quite different. The research has some reference significance to structure design and parameter optimization of the conical hydrostatic bearing.
