摘　　要：同时考虑温度和流体内能及壁面对润滑剂的强作用对润滑剂粘度的影响,在等效粘度模型的基础上,融入温度对润滑剂特性的影响,建立了粘温修正的等效粘度分析计算模型,运用该模型进行了薄膜润滑条件下的轴承特性分析计算,确立了参数与轴承性能的变化之间的关系。By considering the effect of temperature, energy in lubricant and interaction between wall and liquid on the lubricant viscosity at the same time, based on the equivalent viscosity model when considering the effect of temperature on the lubricant characteristic, the calculating and analyzing model of equivalent viscosity with visco-temperature correcting was founded. The performance analysis calculation of bearing was processed under thin film lubrication with this model. The relation of the parameters and bearing performance was confirmed.
