摘　　要：依据传热学、流体力学和摩擦学相关理论,采用有限元数值分析方法,运用Fluent软件,对可倾瓦推力轴承两瓦之间润滑油的温度场进行数值模拟,分析镜板表面温度场在不同转速、表面粗糙度、瓦张角以及粘度条件下,与润滑油的热交换。结果表明:镜板转速、粗糙度、瓦张角以及粘度均对润滑油温度场均产生一定的影响;计算工况下导致滑油温升3~5℃。这一结论可为分析推力轴承进油温度提供参考。According to the theory of heat transfer,fluid mechanics and tribology,using the finite element numerical analysis method and using Fluent software,the temperature field of the lubricating oil between two bearing pads by numerical simulation,we analyse mirror plate surface temperature field at different speeds,surface roughness,viscosity and the pad angle conditions,heat exchange with the lubricating oil.Analytical result showed that the pad angle,viscosity,rotating speed and surface roughness of the mirror plate have an influence on the temperature field of the lubricating oil.Calculated conditions lead to oil temperature rise 3℃to 5℃.This conclusion can provide reference for the analysis of the oil inlet temperature of thrust bearing.
