Chování EHD mazacích filmů za velmi vysokých tlaků - srovnání experimentálních a numerických výsledků

EHL film thickness behaviour under high pressure - comparison between numerical and experimental results

en

This paper is devoted to the study of the behaviour of thin lubricant films under high contact pressures. Central film thickness values obtained from optical measurements are compared with numerical solutions from Zhu and Hu's model. The comparison indicates that both the numerical solutions and the experimental measurements are in good agreement with the Hamrock-Dowson formula at moderate loads and speeds. However, at low speeds and heavy loads accelerated non-linear film thickness reductions shown on the log-log scale are observed in the simulation results and confirmed by the experimental data

Článek shrnuje výsledky studia tenkých mazacích filmů za velmi vysokých kontaktních tlaků. Naměřené výsledky jsou srovnány s výsledky numerických simulací, které předpovídají redukci tloušťky pro velmi tenké mazací filmy.
