Composite Chassis for Formula Student
Mende, Milan ; Šebela, Kamil (referee) ; Janoušek, Michal (advisor)
The Master’s thesis deals with the design and production of a composite chassis of the new formula Dragon X. The carbon prepreg used for manufacturing of the monocoque was to be operated at high temperatures. Therefore, this thesis deals with the application of composites structures in the high temperature environment. The thesis addresses the torsional stiffness problematics and it was not only physically tested, but also simulated by FEM analysis and the results were compared.

Formula Student Composite Battery Pack
Hagara, Matej ; Šebela, Kamil (referee) ; Janoušek, Michal (advisor)
The main goal of the presented thesis is the design and solution to a riddle of a constructive design of a „battery pack“ (battery container) and its installation into the student formula Dragon eD2. The introduction part of the thesis describes the basic FSAE rules, with a focus on the design of the above-mentioned component regarding the pilot’s safety. The main aim of the theoretical part is to introduce the essential and convectional typology and manufacturing processes of composite material’s production, while special attention is given to prepreg technology. The knowledge that was derived from the first part was used to perform a set of mechanical tests and analytical computations. Based on gathered data and information the following simulations were adjusted with intention of maintaining simplicity and efficiency. The emphasis is places on easy and maintainable design, good structural strength, and low weight. The final part of the thesis offers the conclusion based on the obtained results and presents theoretically optimal design in terms of production and installation for low-cost production in small series.

Electric Powered Offroad Motorcycles
Kobza, Tomáš ; Šebela, Kamil (referee) ; Janoušek, Michal (advisor)
This thesis is focused on the study of off-road electric motorcycles, both currently available and prototypes under development. The work describes the history of electric motorcycles up to the present knowledge, construction issues, the types of drive units and batteries used. It compares an electric-powered motorcycle with a conventional-powered motorcycle.

HCCI engines
Otáhalík, Pavel ; Šebela, Kamil (referee) ; Štětina, Josef (advisor)
This bachelor thesis deals with the problematics of HCCI engines. Due to later required knowledge of fundamental principles, the beginning of the thesis is devoted to the history of combustion engines, the principle of their function and their division by basic criteria. The following section consists of the description of petrol and diesel engines in terms of the principle of the mixture formation and its combustion with emphasis on their advantages and disadvantages. In the central part of the thesis, which focuses on the HCCI engines, various mixtures creation methods and ignition are described. Next, the HCCI engines are described in terms of emissions including current concepts solutions. Finally, the conclusion of the thesis consists of speculation of the future of combustion engines and their prospective alternatives.

Formula Student cooling system
Krmíček, Antonín ; Böhm, Michael (referee) ; Šebela, Kamil (advisor)
This bachelor thesis deals with cooling system of Formula Student vehicle with electric drive. The Thesis is divided into three main parts. The first part describes reasons and requirements for cooling, the limits of components and methods of their cooling. The next part is focused on analysis of cooling of single-seater Dragon e1, which obtains the inputs to the design part. Design part contains calculations of losses in inverter and electric motors. The parameters of exchangers and assembly of the cooling circuit are determined. The request is that the operating temperatures are not exceeded during the races. By obtaining more accurate inputs to the calculations, the optimal parameters of the proposed components are achieved.

Engine Block with Integrated differential for Formula Student
Marek, Jiří ; Šebela, Kamil (referee) ; Janoušek, Michal (advisor)
The diploma thesis deals with the design of the integration of limited slip differential of the formula student car into the engine block. To select suitable solution from several considered, a research analysis of possible concepts was first made and then the best possible solution was determined using a decision table. A 3D model was then made for the selected concept based on the original engine block, digitalized by using a laser 3D scanner. The resulting model was then evaluated and built into Dragon X.

Hydrogen as fuel for vehicles over 3.5 t
Alinče, Antonín ; Šebela, Kamil (referee) ; Štětina, Josef (advisor)
This bachelor thesis deals with hydrogen infrastructure for the needs of freight transport: methods of production, transportation, and storage of hydrogen. The work describes the path of hydrogen from production to vehicle propulsion, whether in the internal combustion engine or in the fuel cell. These hydrogen propulsion options are then compared with each other and with other fuels. The conclusion of the work is then focused on the conceptual design of the location of hydrogen tanks in the vehicle.
