Design of vehicle suspension stabilizer
Macháček, Tomáš ; Ramík, Pavel (referee) ; Porteš, Petr (advisor)
Tato diplomová práce je zaměřená na stabilizátory u podvozku aut. První část popisuje všeobecné znalosti vlivu naklonění karosérie na jizdní vlastnosti auta a možnosti konstrukčních řešení používaných v praxi. Dále jsou v této části uvedeny nevýhody použití stabilizátoru a jejich náhrady. Nasledující téma se zaměřuje na soutěž Formule Student a její všeobecná pravidla. Hlavní částí této práce je analýza stabilizátoru Formule Ford, na kterou v poslední části této práce navazuje analýza předního a zadního stabilizátoru Formule Student. Byly vytvořené kompletní MBS modely pro přední a zadní zavěšení včetně stabilizátoru. Díky těmto modelům bylo možné provést výpočty klopných tuhostí a pevnostní výpočty. Z těchto výpočtů bylo možné určit vhodné nastavení stabilizátoru. Všechny modely mohou být dále použitelné pro analýzu jízdních vlastností příslušného vozidla.

Design of Formula Student Front Axle Adjustable Stabilizer
Ševčík, Jan ; Hejtmánek, Petr (referee) ; Porteš, Petr (advisor)
Diploma thesis focuses to design anti roll-bar for Formula Student car Dragon II build in FME. This work follows the proposal anti roll-bar car Dragon I of Jan Krasula. Task of this work is analyses last design, introduce more effective method treatment, create own design with parameters which will be better then last design. An integral part design is prepare manufacture documentation which will be base for manufacture of this komponent

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.

Design of formula SAE front axle
Honzík, Tomáš ; Blaťák, Ondřej (referee) ; Porteš, Petr (advisor)
My thesis will be aimed at front axle design. I am going to design the assembly of the front axle in the program ADAMS by MSC. I am going to observe and record most of cinematic changes of the car such as change of position of vehicle roll centre ,wheel camber, geometry adjustment , wheel toe-in measuring and other necessary data. The final report is going to include strength calculation of particular axle parts. I am also going to solve the axle stabilizer including strength calculation.

Intelligent charger for Pb accumulators
Hadwiger, Tomáš ; Šebesta, Jiří (referee) ; Kratochvíl, Tomáš (advisor)
This bachelor project deals with lead accumulator charging. The properties of this acumulator charger are described here and the best possible way of charging has been based on these properties. The capacity of the accumulators has also been taken into account. The charger itself is able to distinguish between the twelve-volt and the six-volt accumulator. The charger prevents accumulators from overcharging and does not charge damaged ones.It also contains the protection against reversing polarity. The project contains complete scheme, DSP layout, lists of components and their placement on the DPS. The design of the transformator suitable for the charger is also included.

Inverters for lighting units with LEDs
Zuber, Zalán ; Feiler, Zdeněk (referee) ; Klíma, Bohumil (advisor)
The master‘s thesis deals with DC/DC converters for power LED diodes. Gives an overview of the field of LED lighting technology, analyzes various types of converters and shows their principle of operation. Furthermore presents some possible circuit designs for three different voltage levels and the calculations for each part. As an approval of their functionality the results of their measurements are plotted followed by the data evaluation.

Simulation and realization of laboratory DC power supply
Mach, Ladislav ; Koton, Jaroslav (referee) ; Šotner, Roman (advisor)
The thesis deals with analyses of the laboratory symmetrical supplies with adjustable output voltage. It also describes different kinds of current cut-out circuits and several most frequent supply connection schemes. Analyses (simulation program OrCAD) show the characteristics and behaviour of the mentioned supplies. To set the output voltage, operational amplifier structures or linear three-terminal voltage regulator are very often used. The suggested supply was tested and its parameters compared with the simulations. The value of output voltage and current can be controlled with a computer with a USB port. For controlling of the output voltage and current the digital potentiometers were used and controlled by I2C bus.

Tail Units
Dula, Jan ; Mališ, Michal (referee) ; Urík, Tomáš (advisor)
In this bachelor´s thesis is created a survey of constructive solutions and lay-out of horizontal tail unit, solutions of horizontal stabilizer attachment and ways to control the elevator. In the introductory part the term which is used in this thesis are briefly explained. In the following part the possible configurations of the tail units are listed. From these configurations, some solutions are selected and they are closely classified. Any of these solutions provides a short description of the elevator control, the advantages and the disadvantages of this solution, an overview of selected horizontal stabilizer attachment and their detailed description.
