The Elastohydrodynamic Lubrication Analysis of Journal Bearing

Based on the flexibility matrix method, the elastohydrodynamic lubrication performance of journal bearing are studied. Comparisons are made the effect of elastic deformation on the center orbit of connecting rod big end bearing. The results show that bearing eccentricity has far exceeded 1 near the maximum combustion pressure, considering the elastic deformation of connecting rod big end bearing, changing trend of bearing center orbit is the same at other times.
