Urban three-wheeled vehicle with electric drive
Černík, Adam ; Porteš, Petr (referee) ; Tobiáš, Martin (advisor)
This bachelor thesis deals with the conceptual design of the chassis of a three-wheeled. The total payload od the vehicle is 160 kg. At the beginning, the work deals with the search for different types of chassis in used three-wheeled vehicles. The advantages and disadvantages of various chassis concepts and the subsequent choice of one them are also summarized. Then the conceptual parameters of the vehicle are selected. At the end a 3D model is modelled in program Inventor, which corresponds to the selected conceptual parameters. This model is used to visualize the designed chassis of three-wheeled vehicle.

Conversion of Car Front Suspension
Chaura, Václav ; Porteš, Petr (referee) ; Hejtmánek, Petr (advisor)
This diploma thesis is focused on the design of the conversion of the car front suspension for racing purpose. Existing suspension solution is described by analyse static and kinematic quantities. Furthermore, a change of suspension is proposed to improve the driving characteristics of the vehicle, where the kinematic, dynamic and strength analysis of the newly designed suspension is performed. The conclusion summarizes the comparison of the original and the new suspension design.

Race Car Dataloggers
Job, Štefan ; Blaťák, Ondřej (referee) ; Porteš, Petr (advisor)
This work is focused on race car dataloggers. The goal of this work is put on depicting the dataloggers that are used in the time being and also on the data that are measured as well as the information they provide to the driver or racing engineer. The work itself is divided into four main parts. They deal with the basic terms regarding this topic, the description of the dataloggers and of the companies that specialize in the datalogger production. The conclusion contains general evaluation of this work

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.

Concept of Autocross Racing Car
Dobrovolný, Ondřej ; Porteš, Petr (referee) ; Ramík, Pavel (advisor)
Diploma thesis deals with the design and simulation of torsional stiffness of the frame for autocross racing car. The design put emphasis on observe the regulations of international automobile federation and the result of torsional rigidity and weight. The first part focuses on the design of vehicles for autocross and its regulations. The main part is the structural design of the frame, following with simulation analysis using finite element method and computing torsional stiffness. In conclusion, results are evaluate and referred for further development.

Mathematical Model of motor vehicle driving gear
Marek, Petr ; Laurinec, Marián (referee) ; Porteš, Petr (advisor)
The subject of my master’s thesis is creating a mathematical model of motor vehicle driving gear using the software programs MATLAB / Simulink. The results are presented via graphs of the data gained from the simulation of a car driving on a determined track. The parameters used in the model come from a specific file and they can be changed anytime in order to correspond with the particular vehicle.

Design Proposal for the Switching Mechanism of a Tourist Car Headlamp
Škývara, Tomáš ; Porteš, Petr (referee) ; Ramík, Pavel (advisor)
The purpose of this thesis was to create proposal of mechanism for the tourist shutter, which could replace the original solution for projector currently used by Visteon-Autopal. The thesis was focused on background research of known solutions and proposal of new mechanism. The proposal was processed from mechanical site at first. All proposals were created to get inspiration before final design of tourist shutter for projector.

Design of alignment and chassis setup equipment
Vajdák, Martin ; Bradávka, Marek (referee) ; Porteš, Petr (advisor)
Diplomová práce se zabývá návrhem zařízení pro měření parametrů podvozku závodního vozidla (sbíhavost/rozbíhavost, příklon/odklon, světlá výška vozu, rozložení hmotnosti), které následně slouží pro jeho seřízení. Úvodní teoretická část uvádí přehled nejdůležitějších parametrů podvozku, které mají podstatný vliv na chování a ovladatelnost vozu a které jsou tak nejčastěji předmětem zájmu. Následující kapitola shrnuje metody a zařízení, které se dnes pro měření parametrů podvozku využívají a uvádí jejich výhody a nevýhody. Předposlední kapitola teoretické části je věnována obecným doporučením pro měření parametrů podvozku vozidla a jeho seřizování. Poslední kapitola teoretické části uvádí požadavky na zařízení, jehož návrh je předmětem této práce. Úvod praktické části práce je věnován popisu konstrukce dvou navržených variant pro měření parametrů podvozku vozidla. Následující kapitola pak popisuje přípravu a průběh měření s využitím navržených souborů zařízení. Další kapitola je věnována výběru snímačů a zařízení pro měření. Závěr této kapitoly pak shrnuje přibližné celkové náklady na výrobu obou navržených variant. Poslední kapitolou je napěťová a deformační analýza navržené podpěry automobilu, která podepírá automobil namísto jeho kol. Závěr diplomové práce shrnuje dosažené cíle a zároveň uvádí návrhy a doporučení dalšího vývoje navržených zařízení.
