TM 260.02 Experimental Module Optical Elastohydrodynamics Show data sheet (pdf file) Print page
Technical Description
The set-up is operated together with the TM 260 Basic Module. A steel sphere is pressed against the underside of a driven glass disc. The light from a reflected light microscope passes through the glass disc and the film of oil at the point of contact, it is then reflected from the surface of the steel sphere. The thickness of the film of lubricant is determined visually from the colours of the interference rings produced. The microscope is fitted to an adjustable x-y slide and has a focus adjustment. A defined load of up to 200N can be applied to the sphere via a lever.
Learning Objectives / Experiments
· Determination of the thickness of the film of lubricant at the point of contact between a sphere and a flat surface; comparison with theoretical values.
· Influence of load and speed on the thickness of the film of lubricant.
Features
Investigation of the thickness and characteristics of a film of lubricant on a rolling sphere
