Design of hip joint simulator
Žonda, Peter ; Čížek, Petr (referee) ; Vrbka, Martin (advisor)
The master's thesis is concerned with design and execution of an experimental acetabulofemoral joint simulator. Its primary use is the study of lubrication film thickness in hip implants. The work first describes available hip joint simulators, which simulate particular joint positions. Next, the thesis proposes author’s own designs and solutions. The result is a produced device allowing for dynamic change of load in simulation of hip joint flexion and extension as set by ISO standard. Contact is recorded by an optical apparatus composed of a high-speed camera and a microscope. The work also includes the initial testing experiment and the complete design documentation of the device including electrical wiring diagrams.

Influence of the surface roughness features on the next rolling bearing element
Saksa, Vladimír ; Zapletal, Tomáš (referee) ; Košťál, David (advisor)
This bachelor thesis deals with investigation of influence of the surface roughness features on the next rolling bearing elements. It researches changes in the film profile entering into the contact. This thesis describes also elastohydrodynamic lubrication regime by witch each rolling bearing works as well as the difference between fully flooded and starvation contact of rolling ring with rolling bearing element. The part of the thesis is the experiment using different kinds of lubricats from which is visible really influence of these contacts. This experiment is realized on the contact simulator and the film thickness is measured using method of optical interferometry.
