The development of elastohydrodynamic lubrication (EHL) theories and simulation models requires experimental validation techniques. This paper reviews EHL experimental techniques based on capacitance, electric conductivity and contact resistance, discharge voltage, X-ray transmission, R-C oscillation technique, and optical interferometry, and experimental measurements of EHL film thickness. A few trends of film thickness variation with speed at low speed and thin-film lubrication are observed. The numerical results of an EHL model are compared with various experimental results. These experiments are from two thin-film smooth experiments under pure rolling and one multi ridge experiment with different slide-to-roll ratio. Most of these numerical and experimental results are in good agreement.
