Analysis of Deceleration of Trams and Evaluation of its Impact on Standing Passengers
Skupová, Dagmar ; Fleissig,, Petr (referee) ; Vémola, Aleš (advisor)
The thesis is concerned with establishing the braking retardation and determining of it's influence for standing passengers. The thesis consists of three parts. The first part is theoretical and it is engaged in brake system of tramway. The second, experimentally part talks about practical establishing of braking retardation. And the third part of thesis is gived to discussion about established values of braking retardation. The aim of thesis is to find a value of braking retardation, when standing passengers don't fall down.

Design of magnetorheological clutch.
Nováček, Vladislav ; Dočkal, Aleš (referee) ; Roupec, Jakub (advisor)
This thesis deals with the design of the magnetorheological (MR) clutch. The extensive literature research with particular conclusions to each design variant of MR clutches or brakes has been done in the first part of the thesis. The second part of the thesis describes the design of the actual MR clutch based on the results of the analytical calculation of the magnetic circuit. Finally, the experiments verifying the function of the key segments of the clutch, and the whole clutch are summarized in the third part of the thesis.

Filament Winding Machine
Dorňák, Michal ; Hampl,, Štěpán (referee) ; Foller, Bronislav (advisor)
The aim of this diploma thesis is the proposal of solution of three-axial winding machine for winding technology of rotary profile. Winding materials are continual springs of carbon, aramid or glass fibre impregnated by resin. The main construction change of the machine compared to commercial available solutions is the use of linear motor as a frame element instead of roller screws or toothed chain. Linear motors have higher dynamics of the movement and they can reach higher speed compared to other solutions, which guarantee increase of the machine productivity. The main importance is put not only on the functionality but also on the low price of this solution. The 3D model of the mechanism is created in the program Inventor 2009.

Low-speed Wind Turbines for Small and Medium Size Applications
Forró, Bálint ; Paar, Martin (referee) ; Procházka, Zdeněk (advisor)
Bachelor’s thesis deals with usage of slow-running wind turbines for small and medium applications, especially with Savonius rotor. In first part I described theoretical usage of wind and analysis of wind power plants. Next part describes advantages and disadvantages of Savonius wind rotor and its practical usage. Thesis is ended with engineering design of wind rotor of this type for according performance at specific wind speed.

Construction of a brake mechanism
Laštůvka, Martin ; Galas, Radovan (referee) ; Frýza, Josef (advisor)
The bachelor's thesis describes design of brake and arrestment mechanism for high pressure viscometer which is placed in the laboratory of the Institute of Machine and Industrial Design FME BUT. The Brake mechanism is able to brake torque of 50 Nm and the arrestment mechanism allows to stop the shaft at precisely defined angles. When designing the device is used current the state of knowledge.

Stabilizing systems of passenger cars
Odehnal, Jakub ; Vopařil, Jan (referee) ; Kučera, Pavel (advisor)
This Bachelor’s thesis describes basic stabilizing systems of passenger cars. These systems are correcting driving the cars and improve safety of the traffic. The main systems described in this thesis are ABS, ASR and ESP. There are also summarized some other assistant systems. In the end there is also view of various individual car companies and their theories of stabilizing of cars.
