Recent Progress of Elastohydrodynamic Lubrication of Finite Line Contacts

Based on the author's laboratory and published literature, the research status of elastohydrodynamic of finite line contacts are summarized and analyzed. The effects of misalignment, skew, end free surface, grease-lubricated, starvation on the film pressure and film thickness were discussed. The current problem was put forward. The recent research hot spots included the prediction of fatigue life, coupled lubrication and dynamics, parallel algorithm and many others. Finally, it is pointed out that more efforts should be made with respect to the research on the EHL of finite line contacts. As domestic products encountered a transformation from quantity to quality, the demand of precision and working life became higher. The application of theoretical research into the product process has been an urgent subject.
