Original abstract

A newly developed experimental technique, based on colorimetric interferometry, has allowed accurate measurement of central and minimum elastohydrodynamic (EHD)film thickness for a wide range of operating conditions. This study was aimed at determinimg the influence of various material parameters on central and minimum EHD film thicknesses. Obtained experimental data were compared with Hamrock and Dowson film thickness equations and a numerical solution presented by Venner. The results obtained confirmed that the ratio between central and minimum film thicknesses changes significantly with both load and material parameters.
