Original Abstract

In order to predict and optimise highly loaded contact performance, accurate lubricant data is crucial. The lubricants high-pressure rheological behaviour is by far the least known parameter. However, this is the key factor to realistic modeling of non-Newtonian Elasto-Hydrodynamic lubrication. In this paper a new approach is described to extract such data from optical interferometric film thickness measurements of EHL contacts. The approach is relatively straightforward and cheap compared to out of contact rheological experiments using specialized equipment
