Experimental Study of Elastohydrodynamic Lubrication under Heavy Loaded and Variable Velocity Conditions

Abstract:

In order to reveal the elastohydrodynamic lubrication characteristics under heavy loaded and variable velocity conditions, We carried out the relevant experiments by the self-developed optical interference EHL experimental device. Improved apparatus substitute screw for the slider-crank, and driven by stepper motor. Velocity mutation experiment carried out to discuss features of the oil film while the stepper motor speed instantly changes from the velocity of 0.23mm/s, 0.38mm/s and 0.52mm/s. It shows that extrusion effect and oil film sag emerge in acceleration instantaneous similar to zero entrainment speed even it is not, and end of oil film has a necking phenomenon distinctly.
