Original abstract
The ability to predict the in-contact deformation of surface topography is very important for the design of machine components with respect to minimizing the friction and wear of rubbing surfaces. In this study the amplitude attenuation principle is verified as a simple tool for this purpose. Measured lubricant film profiles are compared with prediction based on this principle. From the results obtained it appears that the amplitude attenuation principle provides reasonable estimation of the deformation of rubbing surfaces that can be used for the prediction of in-contact behavior of surface roughness. Good agreement was obtained under pure rolling conditions, which provides a good initial point for the other studies under rolling/sliding conditions where the wear of rubbing surfaces is of key importance.

Článek shrnuje výsledky studia chování reálných povrchových nerovností v nekonformních kontaktech provozovaných za podmínek čistého valení při elastohydrodynamickém režimu mazání. Jeho cílem je ukázat možnosti teoretického přístupu k deformaci povrchových nerovností založeném na amplitudovém útlumu v praktických aplikacích.
