Conception of terrain vehicles UTV
Máca, Jiří ; Vopařil, Jan (referee) ; Kučera, Pavel (advisor)
This review type bachelor thesis is dealing with conceptual solutions of Utility terrain vehicles. Individual chapters are describing main functional groups and different options of their construction. These options are analysed in terms of suitability for given application in utility and sport terrain vehicles, their manufacturing complexity and costs. Specific vehicles are mentioned only marginally.

The impact of tire inflation on driving performance of a passenger vehicle
Pelán, Radim ; Bradáč, Albert (referee) ; Panáček, Vladimír (advisor)
The key goal of the following diploma thesis is to evaluate influence of the air pressure in the car tires on the driving dynamic, stability and comfort. The first part is dedicated to the theory of the driving dynamic, stability, tire parameters and tire inflation. Next practical part is focused on the drivers’ knowledge about the correct tire inflation and follows with the measurements and evaluation of the influence of the tire inflation on the driving characteristics, riding comfort and its comparison. These influences are summarized and followed up by the recommendations for the drivers and also the expert activities.

System comparison of road adhesion measurements
Mikulec, Roman ; Jůza, Petr (referee) ; Tokař, Stanislav (advisor)
This thesis presents a comparison of different methods for measuring road surface skid resistance and an assessment of whether there is a functional dependency in between measurement results of these methods. It consists of a description of the physical quantities, which are measured by these methods and equipment used for these measurements. The work includes the measurement and comparison of measurement outputs with each other. Among the measurement methods there can be seen similar development of their values, with two exceptions there is similar difference between the results of the measurement methods. When comparing the results XL Meter instrument seemed more accurate than the RaceLogic due to its higher frequency of data recording. By using numerical method of comparison between XL Meter device and multipurpose device TRT there was a constant by which the results differed from each instrument, with value of 0,35, using the method of interspacing the resulting differences of values by a line, the resulting constant by which the results differed between the devices had the value of 0,33.

Vehicle Multibody Model - Ride Comfort Evaluation
Friedl, Michal ; Vančura, Jan (referee) ; Blaťák, Ondřej (advisor)
This master’s thesis is concerned of ride comfort. It uses MBS simulation software MSC Adams, especially its Car module. It contains simulations of ride over the road with obstacles that represent the everyday conditions in real traffic. The main area of focus is to find acceleration data that are present on the driver’s seat and co-driver’s seat in relation on specific suspension settings which affect the ride comfort.

Development of Formula 1 cars
Šopík, Lukáš ; Novotný, Pavel (referee) ; Píštěk, Václav (advisor)
This bachelor´s thesis deals with development of Formula One cars from the begging of the Formula One Worlds Driver´s Championship and describes the first twenty years of this development. This period is characteristic as the replacement of the pre-war cars with engine in front for the cars with engine behind the driver, which is typical for nowadays Formula One. There are description of main construction components and their subgroups, which had been improved by using new materials and technologies.

Racing car chassis
Macháček, Tomáš ; Ramík, Pavel (referee) ; Píštěk, Václav (advisor)
Cílem této bakalářské práce je analýza současných konceptů podvozků závodních okruhových aut. V první části práce je zpracován historický vývoj, charakteristika kol a pneumatik s reprezentací dobře známých produktů. V druhé části je popsán systém odpružení, pružné média a tlumící členy. Systémy odpružení je zde rozdělen na nezávisle a polozávislé zavěšení kol a odpružení pevných náprav. Následující oddíl této práce je zaměřený na standardní kontrolní systémy, jako jsou ABS, ESC a TSC. Závěr přináší rychlé shrnutí této problematiky.

Risk analysis of hazardous substances resulting from burning tires.
MATĚJOVSKÁ, Petra
This paper deals with the current world-wide problem of excessive production of tires, especially in the context of emerging high-volume waste after the end of their life. It aims to map the possibilities of how to dispose of old tires and to assess their applicability in practice. Another task is to compare the tire production process with how the tires are treated as a waste product in the Czech Republic over the last nine years. Finally, it is discussed tire fires in the Czech Republic between 2006-2011, which have been dangerous for local residents and the environment. Statistics of production of used tires and treatment with them have shown that in recent years there has been a large increase in both the production of tires, as well as methods and ways to effectively get rid of them once they become waste. The next section outlines the methods which the loading and removal of tires occur, and which should be avoided in the future. The last part contains statistics on tire fires in the last 6 years in the Czech Republic and an evaluation of the most endangered sites and the most common causes of these fires.
