Modular Power Supply for Formula Student
Ščípa, Samuel ; Bohrn, Marek (referee) ; Pavlík, Michal (advisor)
This bachelor thesis is focused on the theoretical analysis and design of switching power supply with galvanic isolation. The implementation of the design is in the form of the power and control part of the modular power supply. The device parameters are suited for the needs and requirements of the development department of the electric student formula. Design configuration achieves a maximum output voltage of 1000 V and a current of 100 mA, which are user-adjustable.

Design of Formula Student Car Wheel Carriers
Chlud, Martin ; Janoušek, Michal (referee) ; Ramík, Pavel (advisor)
Master’s thesis focused on design and construction of front uprights for Formula Student racing car. Topology optimization and FEM analysis will be used to design the uprights with higher stiffness and minimal weight difference compared to the last model. In the FEM analysis loads will be applied from wheel side and from suspension side. Design of the upright then will be compared to the previous designs especially to safety factor, weight and cost.

Graphics Interface for Data Telemetry of "Formula Student"
Martiček, Juraj ; Milet, Tomáš (referee) ; Zemčík, Pavel (advisor)
Thesis focuses on creation of complete telemetric system for data collection and tuning of a racing car in Formula Student competition. This system consists of graphical user interface, which is wirelessly connected to device installed on a racing car. Telemetry provides live data view coupled with recording features. Graphical user interface provides tools for data analysis to be used for development, testing, and even racing of a formula made by the Formula Student team.

Vehicle Front Wheel Carrier Behaviour Analysis
Baxant, Roman ; Janoušek, Michal (referee) ; Ramík, Pavel (advisor)
Master’s thesis is focused on a design of front uprights for Dragon 8 racing car of TU Brno Racing Formula Student team. This thesis follows up the bachelor’s thesis called “Race Car Front Wheel Carrier Design”. Discussion about team’s recent upright and component designs is followed by a model creation with use of topology optimization. Final geometry is simulated in FEA software. Design of the upright is then compared to the previous designs and also to its substitute produced with milling machining process.

Modeling and control of rear driven axle for Formula Student
Kavec, Matúš ; Veselý, Libor (referee) ; Pohl, Lukáš (advisor)
This thesis is focused on design of controll structure of Formula Student monopost. Part of the thesis is a design and subsequent debgging ofthe model so it has the best possible response compared to reality. A PID controller with two degrees of freedom was used to create the control structure. Created controll structure has the task of regulating the system to the required value. By reducing skid, which is often unwanted in race cars, we can achieve better response while accelerating.

Design of Formula Student Wheel Suspensions
Urban, Marek ; Fojtášek, Jan (referee) ; Porteš, Petr (advisor)
Tato práce se se zabývá návrhem kinematiky zavěšení kol obou náprav. Na základě analýz jízdních dat, multi-body simulací v softwaru Adams Car, simulací v Matlabu a analytických kalkulací v Mathcadu, je navržena řada změn s cílem zlepšit jízdní vlastnosti vozu Formule student, tyto změny jsou následně implementovány do CAD modelu vozu. Jednotlivé změny kinematiky náprav jsou provedeny na základě analýzy konkrétního problému, který se snaží řešit. Jednou z problematik je zástavbová náročnost systému odpružení a zavěšení zadních kol, zde je cílem snížit hmotnost, výšku těžiště a moment setrvačnosti. Další problematikou je geometrie předního kola, kde je cílem zlepšit využití pneumatik a snížit síly v řízení. Dále se práce zabývá simulacemi elastokinematiky zadní nápravy, součástí je také návrh měřícího zařízení. V poslední části je zkoumán vliv provedených změn i elastokinematiky na jízdní dynamiku vozu v ustálených stavech za pomocí MM metody simulované s modelem celého vozu v Adams Car a zpracované v Matlabu.

Optimization of axle carier for formula student for SLM fabrication
Vaverka, Ondřej ; Růžička, Bronislav (referee) ; Koutný, Daniel (advisor)
This diploma thesis deals with design of axle carrier for Formula Student. The axle carrier is topologically optimized and additively manufactured with Selective Laser Melting technology. Material for its production is aluminium alloy AlSi10Mg, which has worse mechanical properties than commonly used high-strength alloys. Therefore the aim was, by using topology optimization, to design a component, which would have comparable properties with milled component. The stress strain analysis was carried out by the finite element method and maximum deformation and safety coef-ficients were acquired. The prototype was made and its dimensions were controlled by optical digitization, which proved accuracy of manufacturing. The strength calcu-lations were verified by special testing device and photogrammetry measurement. The load during the tests was 20 % higher than in the analysis and no limit state was observed. This verified its safety and functionality.

Development of control electronics for magnetorheological dampers in Formula Student vehicle
Skřivánek, Vladimír ; Dobossy, Barnabás (referee) ; Adámek, Roman (advisor)
The topic of this bachelor thesis is the design of a control board for magnetorheological dampers. The board has to be able to receive input data from a datalogger over the CAN bus. From these data, it has to calculate the required current using a known control algorithm and has to be able to regulate it by feedback using a PI controller. Furthermore, it should be able to measure the temperature of the magnetorheological fluid in the damper to be able to correct the degradation of the damping force due to increasing temperature. Another part of this work is to test the implementation of this control algorithm and measure the F-v characteristics of the magnetorheological damper for different values of current.
