Abstract
The elastohydrodynamic lubrication (EHL) in a bearing contact is the typical regime between rolling elements and raceways. Simulations carried out by different researchers show a significant influence of harmonic load on the EHL film behavior. The current study aims to validate previous numerical findings using high-speed interferometry measurements to investigate the EHL behavior under force vibrations. A new image processing method is proposed based on the 2D unwrapping algorithm to extract film thickness in both circular and elliptical contacts. The experimental results confirm the previous numerical findings in the literature. Finally, it is shown that the frequency of excitation directly affects the amount and amplitude of the modulation behavior of the EHL film.
