Experimental Investigation of Lubrication Film Starvation of Polyalphaolefin Oil at High Speeds
In this paper, a new test rig for high speeds was developed with the ability to achieve the measurement of the traction force at high speeds up to 100m/s and the lubrication film thickness at speeds up to 42m/s. The lubrication behavior of starved EHL contacts at high speed up to 40m/s was focused on. The influence of centrifugal forces on the asymmetric shape of interference images and the reduction of film thickness are studied. Results under starved conditions are compared with that under fully flooded conditions.
