An Original Methodology to Model Stationary and Transient Starvation in Elastohydrodynamic Lubrication Contact

Résumé

Abstract Despite many researches in the past decades, starvation modeling of an elastohydrodynamic lubricated (EHL) contact is still an arduous task. The well-established Jackobson, Floberg, and Olsson (JFO) theory indeed shows jump discontinuities that are tricky to consider in a numerical solver. Two strategies are discussed in this article. The first one uses a penalty method, while the second one uses a moving mesh method. Their efficiency are compared to reference cases coming from the literature. Then, they are submitted to a transient analysis where the oil inlet layer decreases suddenly.
