Experimental study of lubricant films in contact of machine parts
Kučera, Ondřej ; Křupka, Ivan (referee) ; Vaverka, Michal (advisor)
This bachelor thesis is focused on the description of methods for experimantal study of lubrication films in contact of machine parts, particularly for non-conformal surfaces, for which elastohydrodynamic and mixed of lubrication is typical. The methods are devided according to measured quantity into the methods for film thickness measurement, contact pressure measurement and temperature measurement. It was described the principle of these methods, the equipment, application and characteristics. Finally, evaluation of current status and further development are included.
Friction and lubrication in artificial joints
Vocel, Jan ; Musil, Jan ; Šída, V.
The changes in function of artificial joint could be caused also by inconvenietn lubricant. At present time besides ionic fluids also some water soluble polymers and their derivatives have been investigated. Friction measurements using a technical frictional machine showed low coeficient of friction with negligible wear.
