Tubular Skid Holder of Skoda Fabia Super 2000 Rally Car
Ondruch, Marek ; Žlebek, Jindřich (referee) ; Ramík, Pavel (advisor)
This diploma thesis “Tubular Skid Holder of Skoda Fabia Super 2000 Rally Car” is aimed to engineering design of tubular skid holder of rally car Skoda Fabia Super 2000. There is used FEM software for analysis s evaluation of current variant and following variants of engineering design. The most relevant final variant design, which is consistent with asked stiffness and reduction of weight, was chosen based on findings.

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.

Formula Student Steering System Design
Pospíšil, Jaromír ; Blaťák, Ondřej (referee) ; Ramík, Pavel (advisor)
This thesis describes the steering system parts, the most common used parts and rates their advantages and disadvantages. These findings are then transferred into the Formula Student steering system design. The thesis also presents procedures leading to determine load of steering system, which is taken into account in steering system design. The final version of steering system is analyzed of stiffness.

Design of vehicle suspension stabilizer
Krasula, Jan ; Blaťák, Ondřej (referee) ; Porteš, Petr (advisor)
This master’s thesis is focused on a design of the formula student’s anti-roll bar. The beginning of the thesis is devoted to the introduction of the anti-roll bar function and the explanation of its effect on a vehicle including the analysis of various constructions. Second part deals with the Formula Student competition. There is the analysis of the formula Ford’s anti-roll bar as a starting point for our own design. In the section which deals with the anti-roll bar design several alternatives are designed, the stress analysis of components are made and multi body system models are developed for final solutions. These models serve for further analyses of driving characteristics of the vehicle.

Solution of Gear Drive for Camshaft
Barvík, Rostislav ; Píštěk, Václav (referee) ; Novotný, Pavel (advisor)
For dimensions of crankshaft drive Zetor engine, which is solve by a helical gear drive will be created a dynamic model in MBS (multi body system) and perform analyses. The same way will be created a dynamic model for a spur gear system. In conclusion will be confrontation both of these drive solutions.

Silicone damper of a six-cylinder in-line diesel engine
Drozdek, Lukáš ; Novotný, Pavel (referee) ; Píštěk, Václav (advisor)
This thesis "Silicone damper of a six-cylinder in-line diesel engine " is focused on the proposal of alternative using of silicone damper for the a six-cylinder in-line diesel engine, which is made for tractors and other industrial aplications. The aim of this thesis is to count the oscilation of crankshaft by the help of appropriate dynamic model, then to propose such a basic parameters of silicone damper, which absorbes torsion blip crankshaft to acceptable value. The next part of my thesis is proposal of the constructive implementation of fixation the silicone damper on the free part of crankshaft. The last part of my thesis is comparing and evaluating the oscilation of crankshaft without a dumper and with a new propsal of the silicone damper.

The analysis of boring process of automatic horizontal boring machine
Šohajek, Jiří ; Roubíček, Jiří (referee) ; Bradáč, František (advisor)
The object of this dissertation is to analyse a drilling process of an automatic horizontal boring machine the SVD2 for drilling of bearing holes. There were problems with vibrations during drilling process, causing an extreme noise and this dissertation solves them. First of all it was necessary to analyse the vibrations, to examine a machining process and measure machine dynamics and statics. Another task was to compare measured results with mathematical models and after their analysis to design structural and other solutions. The SVD2 machine was designed on the basis of a previous type the SVD. Its conversion to a new one was based on adding of six spindles. As a result a number of drilled bodies was increased from one to four, so a performance was increased four times. That is why there was an original intention to rebuilt the other two spindle machines. To leave the basical parts of the machine without any modification ( such as a reinforcement of a mount and adjusting of a bigger distance of a side linear spindle guideway and a cross linear guideway of a support for clamping devices), would be unsuitable solution, which was confirmed after a measurement and a following analysis.
