Chassis Electrical Systems
Slaběňák, Patrik ; Kuchyňková, Hana (referee) ; Hájek, Vítězslav (advisor)
Travelling by bus is very extended in present and safety return home is a wish of every passenger. Outcome of this bachelor work is a survey of the most used stability systems, used in cars and facilitating the work of drivers in critic situations. Among others, this work contains the survey of powers acting on a vehicle during the ride. This powers influence impending slippery road on aggravated adhesive conditions. Individual systems are described attentively and supplemented by illustrating pictures, which near this issue and facilitate the real idea of functionality. At the conclusion of this work is mentioned the theoretical suggestion for practical exercising of a subject automobile electrotechnics and also a referring is mentioned to my continuation in this dissertation.

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.

Preliminary aerodynamic analysis of remotely controlled model with jet propulsion
Novák, Ondřej ; Zikmund, Pavel (referee) ; Popela, Robert (advisor)
This bachelor´s thesis deals with aerodynamic analysis of unmanned aircraft and subsequent changes to design of wing, its position and wing-fuselage junction. In this work emphasis is laid on flow separation, its interaction with other flow structures and its influence on aerodynamic properties. The goal of these changes to the aircraft is ensuring sufficient stability and controllability in low as well as high angle of attack flight. AVL, XFLR5 and CFD methods were used in the thesis. In case of inaccuracy of CFD calculation, two backup wing related modifications were prepared.

Rebuilding of VUT 051 RAY into twin-engine conception
Jílek, Jan ; Mališ, Michal (referee) ; Píštěk, Antonín (advisor)
The master’s thesis is dealt with the design of rebuilding of VUT 051 RAY which is equipped electric powerplant to twin-engine conception named VUT 051 RAY-DUO. In the thesis was verified the range of centre of gravity position of VUT 051 RAY-DUO then powerplant in ducted fan configuration was designed, performances of the airplane were appointed and controllability during fail one of the engines was analysed. The design of new powerplant was verified by strength analysis and then costing calculation was established.

Vehicle data analysis
Starý, Přemysl ; Porteš, Petr (referee) ; Zháňal, Lubor (advisor)
The diploma thesis deals with a data analysis of the Formula Student race car. An attention is given for both, vehicle and driver. Processes of braking, turning and balance of car are analysed. Special attention is given to the dampers positions while driving and their settings. Dampers velocity histograms and ride frequencies graph are put together. Algorithms in MATLAB are suggested to reduce requested time for analysis. Scripts for displaying important channels are made. Analyzed data are used to create events which accelerate orientation in record and tell the most important information.
