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.

Study of the two-axle semi-trailers used in the agriculture
Szymeczek, Ondřej ; Hloušek, David (referee) ; Kašpárek, Jaroslav (advisor)
This bachelor thesis deals with tandem trailers connected to tractors and their use in agriculture. Main part of the work is devoted to the structural elements and nodes of these machines. Another part I described by some national and foreign manufacturers of transport equipment used in agriculture. The remain part is devoted to the legislative conditions connected with this issue, the overview of technical parameters of individual product categories and their subsequent critical analysis.

Design of ski landing gear for skiplane with short take-off and landing
Hostinský, Vladimír ; Dubnický, Lukáš (referee) ; Katrňák, Tomáš (advisor)
The aim of this bachelor thesis is a selection of the most suitable ski landing gear for a use on a given STOL aircraft and its installation on the aircraft according to the law regulations and requirements of the aircraft manufacturer. First part is strictly teoretical and deals with existing design variants of an aircraft skis. More practical second part of this thesis starts with a market research, which creates an overview of existing options of ski landing gears suitable for use on the aircraft. Part continous with a reduction of the options and ends with a choice of the most suitable one. Final part is devoted to the problem of an installation of the landing gear to the given aircraft with consideration of existing law regulations.

Stress - strain study fo tractor body
Šnejdar, Radim ; Prokop, Aleš (referee) ; Řehák, Kamil (advisor)
This master thesis deals with the creation of a computational model of the load bearing part of the tractor and the subsequent implementation of the stress – strain analysis. In terms of critical working conditions, it is focused on three different load cases. Based on the results of the numerical simulation, the optimization of key components is further proposed. Modifications of the model and individual simulations of the operating conditions of the tractor body are performed in the Ansys program. Finally, an evaluation of the results, including their comparison, is made.

Solid Edge - Design of Omnidirectional Mobile Robot Platform
Poul, Ota ; Šoustek, Petr (referee) ; Matoušek, Radomil (advisor)
The bachelor thesis deals with design of three and four wheeled omnidirectional mobile robot platform. Design of both platforms is created in CAD software Solid Edge ST4. The result of this work are 3D models of mobile robot platforms for drawing documen-tation and subsequent realisation of platforms using predefined motor units. For both variants of the platform a stress simulation and visualisation were created within the possibilities of applied software.

Hydraulic circle of undercarriage two-way vehicle
Rozumek, Jaroslav ; Tomeček, Pavel (referee) ; Škopán, Miroslav (advisor)
The aim of this diploma thesis is a concept of hydraulic (hydrostatic) circuit of rail – road vehicle drive for the drive on communication and railway. As my work is not related to a specific type of road vehicle dedicated to a drive on railway, my work is of strictly reference nature. On request I was provided by Bosh Rexroth s.r.o. with a hydraulic scheme of two-way undercarriage (see appendix), which is also a source material for the new concept. My work is focused on interests of SaZ s.r.o., which deals with the development and rebuilding of road vehicles into rail – road vehicles. The first phase is focused on the choice of the most convenient component of railway undercarriage in accord with the assignment. The second phase is oriented on the calculation of travel parameters, dimensioning of systems with concretization of typal mark of components. A part of the second phase is also a concept of hydraulic braking system of rail undercarriage. After that follows a complete evaluation, eventually an alternative solution of given problem.

Springing and Damping Systems of Army Vehicles
Kochánek, Jiří ; Hejtmánek, Petr (referee) ; Blaťák, Ondřej (advisor)
Bachelor's thesis is oriented at springing and damping systems of army vehicles. It describes commonly used systems of springing and damping, their advantages, disadvantages and shows examples of constructional solutions for army vehicles. It also contains conceptual design of springing and damping system of an armoured 8x8 army vehicle.
