Active Damping of Electric Machines Platform
Vaške, František ; Houfek, Martin (referee) ; Vlach, Radek (advisor)
This thesis deals with a design of an experimental model of active damping of eletric machinery platform, its mathematical description and control through the use of a computer. It compares various ways of construction, their physical principles and feasibility. The thesis also contains a description of the model made and of the way it is controlled.

Design of experimental model of boiler
Kuba, Pavel ; Sikora, Michal (referee) ; Vlach, Radek (advisor)
This thesis describes the design of experimental model of boiler and identification of systems parameters. Model and measuring unit were designed on basis of research study. Data acquisition module NI USB-6216 was used to measure and transfer data to computer. Programe MATLAB was used to proces data.

Experimental stand for rotational heat pipe verification
Liška, Martin ; Sikora, Michal (referee) ; Vlach, Radek (advisor)
This bachelor thesis presents a design of an experimental stand for testing of cooling effects on electrical machines trough rotational heat pipe and mainly with design and construction of experimental stand, that represents rotational heat pipe of real machine rotor. Pipe is heated by means of resistance conductor winding and average temperature on a pipe surface is scanned with a additional parallel winding. Experimental stand was designed for subsequent experiments and for evaluating of rotational heat pipe parameters.

Design of wind tunnel
Klusoň, Vladimír ; Sikora, Michal (referee) ; Vlach, Radek (advisor)
The thesis deals with making a device for measuring air technique constants, so-called a wind tunnel. The wind tunnel is used for development of eletric machines aeration systems. Refrigeration of various types of eletric machines ( e.g. asynchronous engine ) can be tested by means of it. The thesis consists of three parts. The first part contains a description of the whole device in single components. With each the component the text concentrates on both the related general theory and a delineation of the implementation itself. The sequel part is devoted to testing the product, i.e. verification of its functionality and airtight sealing, . The third part of the thesis concludes the text by evaluation of resultant solution of the problem.

Design of satellite transmitter pylon.
Kovář, Pavel ; Sikora, Michal (referee) ; Vlach, Radek (advisor)
There is solved a task “Design of satellite transmitter pylon” in this bachelor‘s thesis. Type of the satellite transmitter pylon structure is designed for application level 24 meters – it is location of satellite transmitter. There is one limitation only, constant trianguloid cross-section of the pylon. This thesis presents engineering design and evalution of the pylon.

Využití MKP pro analýzu netradičního chlazení servo pohu
Vlach, Radek ; Pásek, Michal ; Grepl, Robert ; Krejčí, Petr
This project is concerned with non-convectional servo machine cooling using heat pipe. The aim was created computational model using finite elements method. The thermal model was built in software ANSYS 11. The thermal model using finite elements method was used for the check of such cooling. The aim was to examine the possibilities of using heat pipe for cooling of servo. The servo is possible overloaded using heat pipe, because heat pipe effectively reduces heating of machine.
