摘要：
This paper describes a study of point contact elastohydrodynamic(EHD)lubrication behavior at high speeds(up to 20 m s1).Central film thicknesses were measured by optical interferometry device.The influence of slide-roll ratio and operating temperature on the central film thickness was determined.The influence of thermal effects on the reduction of film thickness was discussed via the analysis of numerical simulation method considering thermal effects.Subsequently,the experimental data was used to amend a set of unified parameters for the thermal corrections for different types of oil at high speeds.
