TEST RIG FOR MEASUREMENT OF FILM THICKNESS IN TRANSIENT POINT CONTACT USING INTERFEROMETRY
Keywords:
tribology, contact analysis, experimental stand, interferometryAbstract
The film thickness computation in the lubricated contacts is very important in order to assess lubrication conditions. Although a great variety of experimental methods has been developed, an experimental determination of the film thickness distribution is generally difficult. The optical interferometry is often used to assess the parameters in the elastohydrodynamic (EHD) lubricated contacts, like the film thickness or the contact pressure. This paper presents an original design for a test rig capable of simulating the contact transient conditions. The entraining velocity and the loading are varied following sinusoidal or triangular laws, for three different frequencies.
