Formula Student Tubular Frame Design
Ratiborský, Pavel ; Dundálek, Radim (referee) ; Ramík, Pavel (advisor)
This thesis deals with the design of the tubular frame for the Formula Student car competition. The first part is a brief introduction to the competition and used variants of frames. The main part starts with a list of restrictions by the rules and other necessary installation components. The central part is devoted to the draft modifications and their assessment in terms of torsional stiffness by FEM analysis. The final section presents the resulting frame design with respect to the required properties. The work is concluded final evaluation.

Modern turboprop engine for aircraft to 5700kg MTOW
Košař, Miroslav ; Nastálek, Ondřej (referee) ; Šplíchal, Miroslav (advisor)
This bachelor’s thesis contains a database of available turboprop engines with power up to 2000 kW for aircraft with take-off weight of up to 5700 kg. It briefly mentions basic information about turboprop engines. The main part contains an overwiev of chosen engines and their comparison in the form of tables and graphs. Furute predictions are briefly mentioned in the ending.

Aircraft Engines till the End of WWII
Falta, Libor ; Drápal, Lubomír (referee) ; Dundálek, Radim (advisor)
Bachelor’s thesis deals with aircraft piston engines until end Second World War. Thesis surveys about known, the most use and non-traditional types of engines in timeline. At the beginning it deals about history of aviation and the first use of piston engine as power source energy for controlled flight. There are high requirements on aircraft piston engines. Improving construction and increasing output of engines. In every chapter typical construction and the most powerful engines of the period are described. Thesis includes influence of both World Wars and some prestigious racings, which considerably accelerated global development. Explain the limit for increase output of piston aircraft engines in the last part.

Automotive Gear Lever Design Improvement
Hajdušek, Zdeněk ; Porteš, Petr (referee) ; Ramík, Pavel (advisor)
Zdeněk Hajdušek Automotive Gear Lever Design Improvement BW, IAE, 2010, 59 pp., 75 fig. When designing improvement of the gear lever, solution of higher stiffness and lower mass in compare to the old design has been designed while keeping a necessary safety ratio. A new attachment of the gear lever to the car´s frame which increases lateral stability of the lever has been designed.

Conceptual design of two-seat high performance car
Straka, Martin ; Blaťák, Ondřej (referee) ; Porteš, Petr (advisor)
is diploma thesis deals with design concept of two-seater sports car with the main focus on chassis torsional stiffness and axle kinematics. The main idea started with some paper sketches which were later transferred to the 3D model with all the main parts (engine, differential, driver etc.) using CATIA V5 design program. Then the torsional stiffness was counted using FEM software ANSYS 12.0. Finally the axis geometry during bump/rebump movement of the wheel was simulated in MBS system ADAMS 2007.

Design of scooter
Oulehla, Jakub ; Rubínová, Dana (referee) ; Rajlich, Jan (advisor)
The topic of this bachelor‘s thesis is design of children's scooter of a higher price category. It solves basic ergonomic problems such as machine weight, height and length of deck, and height of handlebars. The goal is to solve these problems and create a scooter that is different of the current production, especially on the domestic market. The design has taken into account the safety, functionality and manufacturability of the machine. The color solution is adapted to the fact that the scooter users will be children.

Analysis of the structure for the effects of earthquakes
Švejcar, Martin ; Martinásek, Josef (referee) ; Vlk, Zbyněk (advisor)
This master thesis deals with analysis of a selected construction subjected to a seismic load. In the Dlubal RFEM programme, a basic model was created and analyzed with the spectral analysis using response spectra and with the time analysis using accelerograms from the database of the programme. The outcomes from these analyses were compared. Subsequently, the same calculations were performed on modified models and the results of the internal forces and deformations of the structure were compared with the outputs obtained on the original basic model.

Design of 3 MW high-speed permanent magnet synchronous motor
Bořil, Michal ; Bárta, Jan (referee) ; Vítek, Ondřej (advisor)
The thesis theme is the design of 3 MW high-speed permanent magnet synchronous motor. The work is divided into several parts, and contains the information given on the topic. The first part lists trends and new technologies of high-speed electric machines, and the issues and construction of high-speed synchronous machines are also listed here. In the second part, the machine is analytically designed from the specified values, which is then modelled in the RMxprt program. In the penultimate part, the engine is simulated by programs that are included in the ANSYS Electronics Desktop package, they are RMxprt and Maxwell. The modified engine model in RMxprt is simulated using defined formulas and then converted to Maxwell 2D, where the engine is simulated using the finite element method. In the last part, the results from the analytical calculation are compared with other high-speed machines. In addition, the results of simulations from RMxprt and Maxwell were compared in the last part.

Development and influence of the weight of cars and motorcycles
Valtrová, Martina ; Fojtášek, Jan (referee) ; Zháňal, Lubor (advisor)
This bachelor's thesis contains the description of the evolution of weight of automobiles and motorcycles. The first chapter contains a description of automobile dynamics and the influence of weight on dynamic properties of a vehicle. To describe the evolution of weight better, there are more detailed descriptions of weight evolutions of certain types of vehicles. The research of historical evolution and technology used today serves as the basis for the main outcome of this thesis, which is a prediction of the future development. This is the content of the last chapter.
