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.

Stroke mechanism of bridge crane
Jirásek, Jiří ; Kašpárek, Jaroslav (referee) ; Škopán, Miroslav (advisor)
This bachelor thesis deals with the design of the lifting mechanism of the crane cat, for a bridge storage crane with a load capacity of 8,000 kg. The thesis contains a critical research of similar existing solutions and the selection of the appropriate concept. The design includes calculations of the basic parameters of the stroke, and based on them selects appropriate rope, pulleys, and design of the rope drum. Furthermore, there are calculated and selected suitable components of the stroke mechanism such as electric motor, clutch, brake and gearbox. The last part deals with the design of the bearing, the drum pin and the calculation of the shaft key. The output of the work is the technical drawing of the whole assembly of the mechanism and the welding subassembly of the rope drum.

Optimization of the existing construction of magnetorheological clutch
Bedřich, Miroslav ; Růžička, Bronislav (referee) ; Roupec, Jakub (advisor)
This work deals with the reconstruction of magnetorheological (MR) clutch. The extensive research on the use of magnetorheological technology in practice was developed in the first part. The function of MR dampers, MR brakes and MR clutches were described. Some parameters of MR clutches were listed and compared. The second part concentrates on construction modifications to improve some parameters of MR clutch. The experiments verifying improvement of operating parameters of MR clutch were carried out in the third part.

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.

Stroke mechanism of crane trolley
Galas, Radovan ; Malášek, Jiří (referee) ; Škopán, Miroslav (advisor)
Bachelor's thesis deals with design of stroke mechanism of crane trolley loads for the weights which do not exceed 5 000 kg. This thesis divided into written and practical sections. Written part deals with the calculation of the principal dimensions of lifting and stress control of cable reel. In this work there are also given reasons for choosing certain key parts of the lifting mechanism, such as: electric motor, gearbox, etc. Prior to the calculations in each chapter there is usually located a short introduction of the topic. The practical part contains a drawing of the complete lifting mechanism, cable reel assembly and two production drawings.

The bridge crane's travel mechanism
Žid, Miroslav ; Nezbeda, Jiří (referee) ; Škopán, Miroslav (advisor)
The aim of this master thesis is to design replacing the central drive of the overhead crane with dislocated drives. It´s a tong crane with the lifting capacity of 63 tons, located inside the hall. In the thesis is processed functional calculation of two types of drives, the associated types of brakes and the coupling element. Next there is a strength control of a new mechanism seat and a selected components. This whole leads to the output, which is the drawing documentation.

Rallye Championships and Used Engineering Including WRC Series
Novák, Pavel ; Porteš, Petr (referee) ; Ramík, Pavel (advisor)
The content of the bachelor thesis is an overview of the current condition of technics used in the car racing competitions focused on the WRC serial. The thesis is diveded into five parts. The first part introduces the contemporary car competitions and FIA federation. The second part is focused on specification of the WRC cars. The third part familiarizes with the organization process of the WRC championship. There are introduced crews with their teams and their results in the constructor cup. The main attention is given to the parts four and five which deal with the contemporary engineering used in WRC and the development trends in this field. There are given methods of virtual designing, computer simulation and testing. In the conclusion of the thesis there are mentioned examples of WRC car development and solutions assumed for the serial cars from the WRC technics.
