Starvation is the regime of elastohydrodynamic lubrication which is designated with thinner lubrication films than fully flooded regime. Paper summarizes main aspects of starvation and deals with differences in area of experimental investigation of starved lubrication phenomena in comparison with fully flooded regime. Thinner lubrication film creates obstacles in experiment process and data evaluation. Effect that can be neglected in the fully flooded regime can create obstacles. and Obsahuje seznam literatury
The aim of the paper is to present transient calculations of an elastohydrodynamically lubricated (EHL) point contact. The paper focuses on the description of the numerical algorithm used to model non-smooth contacts with surface feature on one of the contacting bodies. Results of film thickness and pressure distributions of a selected surface feaure are presented. Simulations were performed and compared for two different rheology approaches (Newtonian, resp. non-Newtonian). and Obsahuje seznam literatury
