Název v původním jazyce

Effect of surface dents on contact pressure in elastohydrodynamic contacts

Popis výsledku v původním jazyce

Nowadays film thickness measurement techniques can provide precise data for the detailed studies of the behaviour of lubricated contacts including transient operational conditions. Contact pressure is in relation with deformation of rubbing surfaces, which can be derived from experimentally evaluated film thickness. Even though the pressure distribution evaluated from measured film thickness is very sensitive to its accuracy, this approach represents a powerful tool for elastohydrodynamic pressure determination thanks to the relative wide availability of film thickness measurement techniques. Chromatic interferograms can be captured within a few microseconds so that this approach seems to be promising in obtaining relevant pressure data even within non-smooth lubricated contacts. This paper presents the results of the effort to extend the applicability of the pressure-film thickness evaluation approach to the non-smooth surfaces. It was found that the main problem is to obtain the film
