Ball-Joint Limited Heating during Accelerated Testing
Kříž, Ondřej ; Porteš, Petr (referee) ; Ramík, Pavel (advisor)
The object of this work is design model of ball joint and define boundary conditions for real condition representation as most exact as possible. Then set parameters of test in TRW-DAS, a.s. for prevention of reacceleration with change of failure mode. Summary of ball joints, their testing and accelerated tests is in the beginning of the work. Next part describes ball joint creation in Pro/Engineer, transfer to Ansys, preparing to solution, fatigue test evaluation and comparing with create model.

Design proposal and modal analysis of fixture for CubeSat vibration tests
Pospíšil, Jakub ; Bartoněk, Jaroslav (referee) ; Lazar, Václav (advisor)
Hnutí CubeSatů se v současné době těší vzrůstající oblibě, především díky možnosti zapojení širšího okruhu institucí do vesmírného výzkumu. Tento zájem zároveň vyvolává nutnost provádět mechanické zkoušky CubeSatů dříve, než je bude možné vypustit do vesmíru. Tato závěrečná práce zpracovává problematiku mechanických zkoušek u CubeSatů a provádění jejich vibračních zkoušek. Na základě této rešerše je proveden návrh přípravku o velikosti 6U včetně modální analýzy a ověření vyrobitelnosti.

Optical Characterization of Thin Films Using Evolutionary Techniques
Horáček, Miloslav ; Bidlo, Michal (referee) ; Jaroš, Jiří (advisor)
My master's thesis deals with creating of a suitable evaluation technique that optimizes the optical parameters of the thin films according to the specified requirements of the proposer. This technique will be used at the Faculty of Mechanical Engineering and it should facilitate the evaluation of measurement results of the The Institute of Physical Engineering workers. Research workers use a digital imaging spectrophotometer for some measurements of optical properties of thin films at the institute. My most important task is to process the output data of the spectrophotometer concerning selected thin film. Construed master's thesis describes all the tools and techniques that have been used for the implementation of the program including evolutionary techniques and basics of the thin films optics (within the framework of the electromagnetic optics). As an enclosure, an electronic medium with the source codes of the whole application is provided.

Napěťová analýza radiální náhrady vřetenní kosti v loketním kloubu
Hlavoň, Pavel ; Florian, Z.
The paper is focused on computational modeling of elbow articulation with radial head replacement. The main part of the project is aimed towards the creation of computational model of suitable partial endoprothesis of proximal part of the radial bone tissue which would keep the function of the elbow articulation while replacing the distance created by resection. The geometrical and computational model of particular radial head replacement and elbow joint were created and analyzed. Computational model with that implant was compared with given physiological state of elbow articulation. The influence of friction and material characteristics of bone tissue and cartilage on changes in contact pressure (and therefore to the abrasion) were analyzed using this model.
