Magnetostrictive materials for mechatronics
Rusková, Miroslava ; Kovář, Jiří (referee) ; Hadaš, Zdeněk (advisor)
The aim of this work is to outline and use or application of magnetostrictive materials and possibilities of mathematical modeling their behavior. Magnetostrictive is the physical character of the material, occurs in the most ferromagnetic materials and leads to many effects. Magnetostrictive materials are more often used to in various branches of engineering.

Transition of cavitating flow to supercavitation
Chovanec, Radomír ; Fic, Miloslav (referee) ; Rudolf, Pavel (advisor)
Bachelor thesis consists of two parts. The first part is dedicated to research. It deals with clarifying the basic concepts of cavitation and current knowledge in the field of supercavitation. The second, experimental part is devoted to flow in Venturi nozzle in the transition from developed cavitation to supercavitation. The aim was to examine the hysteresis that occurs with a change of transition direction. To clarify the phenomenon were compared static and dynamic characteristics acquired from the measurement and visualization on the hydraulic circuit with cavitation jet.

Dynamic Model of Air Suspension System
Janečková, Radka ; Zháňal, Lubor (referee) ; Fojtášek, Jan (advisor)
This master’s thesis is about creating a dynamic model of pneumatic suspension. At first reader gets to know some general information about pneumatic suspension like: classification of this type of suspension, historical development and how modern air suspension systems work. Next, there is review of some created analytical models of this type of suspension. Last but not least, the new dynamic model of air suspension is created in the software ADAMS/Car. It is tested in different types of analysis, such as quasistatic or dynamic suspension analysis and then the model is implemented in the full vehicle Tatra T158 4x4 and more analysis are made. The new model is then evaluated in terms of pros and cons.

Characterization of two-dimensional electromagnet
Kimák, Jozef ; Němec, Petr (advisor) ; Olejník, Kamil (referee)
Abstract:In this work we studied magnetic field magnitude and direction ge- nerated by a prototype of 2-dimensional electromagnet, which was recently cons- tructed in Laboratory of the OptoSpintronics. This electromagnet is formed by two pairs of coils with a mutually perpendicular position of their poles. In parti- cular, we revealed that, by appropriately setting the current through the coils, it is possible to rotate reproducibly the field direction in the plane of the poles for the field magnitude of about 200 mT. We also observed that the generated field is rather homogeneous in a region with a radius of about 5 mm, which corresponds to a typical sample size. On the other hand, the functionality of the electromag- net at lower fields could not be tested unambiguously due to technical problems with a home-made detection Hall probes. This problem will be addressed in the following work. 1
