Electric Off-road Vehicle for Children Axles
Dlouhý, Filip ; Blaťák, Ondřej (referee) ; Hejtmánek, Petr (advisor)
The diploma thesis deals with the design of the chassis structure for an electric off-road vehicle of the crosskart type. In the first part, the research part of the sub-components that are used for the construction of these vehicles is briefly mentioned, including their aspects that must be known when designing the vehicle. The second part describes the actual design of the front and rear axle structure, which was optimized in the program Adams Car and then a model was created in the program Solidworks. The entire design of the chassis was constructed with the intention of assembling the chassis from commonly available components that are currently on the market.

Design of an Electric Velomobile
Starý, Ondřej ; Blaťák, Ondřej (referee) ; Hejtmánek, Petr (advisor)
The aim of this diploma thesis is the design of an electric velomobile, more precisely its front axle and bodywork, as one of the possible alternatives to cars for cities. First, a research analysis of the available electric velomobiles is carried out. In the next step, which is the design of the electric velomobile itself, the parameters and characteristics of the vehicle are determined. The design of the front axle is based on these. The design and optimization of the suspension geometry, its calculation, steering, and their construction design solutions are carried out here. At the end, the design of the bodywork is made.

Zhodnocení konstrukčních řešení vybraných transportních přívěsů pro přepravu sklizňových adaptérů o šířce záběru větší než 9 m
PETRÁŇ, Pavel
Trailers for the transport of combine harvesters headers have undergone relatively large design and conceptual changes in recent years, which have necessitated an increase in the working width of the headers and their safe transport on roads. The design of different manufacturers differs. In this diploma thesis I focus on the current offers on the market of transport equipment for combine harvester headers and their technical solutions. The practical parts diploma thesis also deals with the evaluation of the concept and construction of trailers, evaluation of user experience and analysis of towing curves, which fundamentally affect the passability of the set. A summary and evaluation of the above properties will assist operators in selecting these transport machines.

Design of Vehicle Steering
Barančoková, Zoja ; Rozsíval, Jan (referee) ; Blaťák, Ondřej (advisor)
This bachelor thesis primarily deals with the design of vehicle steering, as it forms one of the most important elements of the overall vehicle. The steering must meet certain safety requirements and nowadays, the driver’s driving comfort is already seen as an essential part of it. This work contains the basic kinematic settings and a summary of the individual constructional components together with their functions. To ensure the correct control of the vehicle on the road, the correct setting of the dynamic part of the steering is also necessary. Bearing in mind the electronic equipment of the vehicle that made its way into spotlight, the thesis also explains principles of the systems operations that every modern vehicle already contains. Finally, the types of gearboxes and power steering which this year’s passenger and commercial vehicles are equipped with are summarized. Based on the acquired knowledge, a prediction of the future development of the vehicle driving is presented.

The concept of consciousness its components and functions in the process of system functioning in the understanding of Karl Wolfgang Deutsch
Pulicar, Miroslav ; Váňa, Tomáš (advisor) ; Franěk, Jakub (referee)
This bachelor thesis deals with the concept of political consciousness in the understanding of the German political scientist and international relations theorist Karl Wolfgang Deutsch. In the first, theoretical section it introduces some existing approaches and conceptualizations of consciousness in political science. Consequently, it provides an essential introduction to Deutsch's communications theory, its basic points and some crucial concepts, such as information, feedback, memory, or will. The aim of this section is to outline the specifics of Deutsch's communication-based approach to the analysis of political systems and provide context for the main subject of this thesis. After general introduction it deals with the very concept of consciousness. Through the analysis of Deutsch's pivotal work The Nerves of Government it outlines theoretical foundations of his concept, defines its functions and significance within the political system, connects it with other concepts of Deutsch's theory and marks some differences compared to approaches of other political scientists. In the second, practical section theoretical considerations developed in the previous section are on the basis of qualitative research applied on the specific political system. The aim of the research is to explain some of the...

Front Axle of a High-performance Sports Car
Hrudík, Jan ; Blaťák, Ondřej (referee) ; Drápal, Lubomír (advisor)
Tato diplomová práce byla psána při studentské zahraniční stáži, pod záštitou Evropské Unie – program „ERASMUS Student Mobility for Placement“. Stáž byla absolvována mezi prosincem 2010 a květnem 2011 ve společnosti a.d.Tramontana, mající sídlo v Palau de Santa Eulália, Španělsko. Pro kompletní návrh podvozku a odpružení jakéhokoli vozidla je nezbytná znalost mnoha technických disciplín. Tato diplomová práce se zabývá dvěma z nich – odpružení a řízení. Nejprve je rozebrána teorie, na kterou se může navázat v praktické části práce. Velká pozornost byla věnována srozumitelnosti textu a názornosti obrázků, bez zbytečných detailů, avšak bez vynechání důležitého. Tuto práci je tedy možné užít jako prvního kroku před návrhem podvozku. V další části je popsáno, jak byla probraná teorie využita při návrhu řízení u skutečného vozu, přičemž největší pozornost je věnována Ackermannově teorii řízení a geometrii zabraňující samořízení při propružení. V závěrečných částech je pozornost věnována ukázce některých z každodenních činností v malosériové výrobě automobilů – jde o zjištění maximálně možného pohybu kola při propružení a proces výroby příčných trojúhelníkových ramen včetně návrhu jejich připevnění k šasi.

T1 Category Race Car Design
Šťáva, Martin ; Vančura, Jan (referee) ; Hejtmánek, Petr (advisor)
This diploma thesis deal with conceptual design of racing car of T1 category. Car consist of tubular frame, front and rear double wishbone suspension, braking system and conceptual design of the fairing. These are the basic of this thesis. For the completeness of the design, the location of the crew and the placement of the components inside the frame are also proposed. Adams Car 2016, Autodesk Inventor 2016, Ansys Workbench 18.1 were used for designing, testing, simulation and calculations. Designed T1 category race car meets International Automobile Federation (FIA) technical standards and safety regulatons.

Stanovení poloměru otáčení u traktorů Zetor Forterra 140 HSX, Zetor Proxima 120 Power a Zetor 7745 Turbo pro potřeby počítačových modelů
ZLOCH, Jan
The main aim of this diploma thesis is to determine the radius of rotation of selected tractors (Zetor Forterra 140 HSX, Zetor Proxima 120 Power and Zetor 7745 Turbo) on three different types of surfaces using different speeds. The literary part deals briefly with the importance and historical development of tractors, the basic knowledge of traction theory, the problems of forces acting on the rolling wheel, and last but not least the construction of the tractor parts. The practical part is mainly focused on determining the radii of rotation of individual tractors on three specified types of surfaces using the three given speeds. The discussion is mainly focused on comparing the radii of rotation meeting ČSN 30 0552 with the radii given by the tractor manufacturer.

Stanovení poloměru otáčení u traktorů Zetor 6911, Zetor 7745 a Zetor 7711 pro potřeby počítačových modelů
ŠŤASTNÝ, Filip
The subject of the bachelor's thesis is Determining the turning radius of selected agricultural machinery. It deals with the analysis of working machines, sorting the tractors out according to multiple aspects and factors that influence the operation of vehicles in the field, such as wheel slipping, rolling resistance , air resistance or strength of the underlying material. Practical part deals with evaluation of measured results of Zetor 6911, Zetor 7711 and Zetor 7745 wheeled tractors and determination of turning radius. Work reflects the actual turning radius of particular tractors and weather conditions during the data collection. For better clarity, the results are written in the tables.
