Experimental study of friction in articular cartilage
 Praus, Tomáš ; Vrbka, Martin (referee) ; Rebenda, David (advisor)
This thesis deals with the experimental study of friction in articular cartilage. After the introduction to biotribology, there are described a principle of measurment on the Mini-Traction Machine and a brief description of machine itself. After that, there is a propose for a preparation and storage of cartilage samples, construction of the adapter into the MTM and research of the friction coefficient. The results of experimental research showed the negative effect of storing the samples in the refrigerator. On the other hand, the measurement of the friction coefficient of the samples stored in the freezer showed the preservation of the mechanical properties of cartilage. Even load and speed of loading have a big effect on friction. When the speed increases, the coefficient of the friction increases too. There is an extreme increase of the friction at higher speeds. But with increasing load the friction coefficient decreases.

Using of experimental apparatus Mini Traction Machine for study of frictional properties of lubricated and unlubricated contacts
 Wilhelm, Pavel ; Ficza, Ildikó (referee) ; Vrbka, Martin (advisor)
This bachelor thesis focuses on description of Mini-Traction Machine test rig. After the theoretical introduction to Tribology is first generally described the principle of measuring on the Mini-Traction Machine and then are described the individual accessories. Consequently the results of main experiments where Mini-Traction Machine test rig was used from all over the world are summarized. Individual experiments show the possibilities of applying Mini-Traction Machine when measuring the material tribological characteristics.
