Behaviour of lubricated contacts under high-sliding conditions
 Adam, Jakub ; Vimmr, Jan (referee) ; Omasta, Milan (advisor)
The aim of this diploma thesis is to describe the influence of individual operating parameters on thickness and temperature distribution of elastohydrodynamic contact under high slip ratio. In this work, the distribution of the lubricant film thickness is determined by optical interferometry and the temperature mapping in EHL contact is realized by infrared microscopy. Two optical filters were used to separate the radiation of contact surfaces and oil. Temperature of disk surface was measured using a sapphire disk with chromium layer that shielded radiation from ball and oil. The experimental device was modified to simulate the conditions of the various vectors between entrainment and sliding speed. The results extend existing information about behavior of EHL contact under high slip ratio conditions.
