Film thickness distribution during the start-up of smooth surfaces.
Manga, Martin ; Křupka, Ivan (referee) ; Svoboda, Petr (advisor)
Bachelor thesis is engaged in experimental study of start-up of smooth surfaces under the conditions of mixed and elastohydrodynamic lubrication. Start-up is non-stationary process, whereat the surface doesn’t need to completely separated with lubrication film. Therefore it exists a real risk of failure. Study summaries all present studies and extends with own experiment on the equipment of tribological laboratory. The evaluation of the experiment was made by chromatic interferometry. This method is used to measure thin lubrication films. Experiment for miscellaneous values of acceleration confirms the findings of previously studies.
