Abstract
Equivalent viscosity model is regarded as the base in this paper. It is considered that lubricant viscosity varies as the temperature. Calculating and analyzing model of equivalent viscosity with viscotemperature correcting is founded. The performance analysis calculation is processed under thin film lubrication. The change law of bearing performance is obtained at different parameters.
