Original abstract
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 feature are presented. Simulations were performed and compared for two different rheology approaches (Newtonian, resp. non-Newtonian).

Cílem článku je prezentovat nestacionární matematický model elastohydrodynamicky mazaného (EHD) bodového kontaktu. Článek popisuje numerický model pro simulaci přechodu povrchové nerovnosti přes kontaktní oblast. Článek dále porovnáva průběhy tlaku a tloušťky mazacího filmu pro dva různe reologické modely – newtonské a nenewtonské mazivo.
