Strain and stress analysis of the car front part under impact loading.
Hrubý, Jaroslav ; Vémola, Aleš (referee) ; Vrbka, Jan (advisor)
This work deals with the stress and strain analysis of the car front part of Škoda Octavia II. generation under impact loading using an explicit formulation of finite element method (FEM). The aim of this work is examination of resistance of the car front part under this impact loading and comparison of the data, which were get out of the FEM simulation of the car impact on the rigid wall with methods, which are used in forensic engineering. The comparison of the FEM simulation of the car impact on the rigid wall will be provided with the correlation method and with the method of energetic grid.

Steam turbine
Vališ, Petr ; Novotný, Zdeněk (referee) ; Fiedler, Jan (advisor)
Goal of this dissertation is design of rotary reduction for entered input parameters that it is connected in parallel with reducing station. Further I´m looking into thermodynamic calculation of stage and chosen parts of turbine, making of project design of connection of rotary reduction to steam circulation. Dissertation is concluded by designed cross-section of turbine.

Traffic characteristics of 2+1 arrangement
Kabeš, Luboš ; Čepil, Jiří (referee) ; Radimský, Michal (advisor)
The thesis discusses the roads in lanes 2 + 1 arrangement in the country and abroad. It focuses primarily analogy of this type of arrangement in our situation, ie on stretches of roads I. classes with an increased number of lanes for slow vehicles to climb. Part of this work is to verify some of the traffic, including traffic flow characteristics compared to conventional two-lane roads, especially in terms of: sectional speed; overtaking; Accident and dependence longitudinal gradient. The work aims to evaluate the foreign experience and achievements of domestic communications options for application configuration 2 + 1 in the Czech Republic.

Selected ČSN Road Design Elements Optimization
Stránský, Jakub ; Čepil, Jiří (referee) ; Kosňovský, Michal (advisor)
The master‘s thesis focuses on the optimization of the design values of curves of the horizontal alignments of the roads. It deals with the comparison of values between czech and foreign standards and differences between them. The practical part examines the values of the real speeds of vehicles passing through the curves of various parameters that were measured during measurements of selected curves during 2014. From these data a new design values are derived that could be used for the design of horizontal alignments.

Analysis of the acoustic signal to detect the speed of vehicles
Koníčková, Tereza ; Beneš, Petr (referee) ; Klusáček, Stanislav (advisor)
The aim of this Bachelor thesis is to create software for sound signal analysis of a passing car with the aim to determine the driving speed. This work describes single methods of a car velocity measurement and it is submitting a new method of velocity measurement with using the Doppler principle at sound signal analysis. My work proved, that it is possible to use this method to determine the speed of vehicles.

Electric and Hybrid Vehicles Analysis
Slaběňák, Patrik ; Kuchyňková, Hana (referee) ; Hájek, Vítězslav (advisor)
Nowadays, oil resources start to decrease, therefore it is necessary to think about alternative sources of energy. The result of this semester project is a basic overview of the current development of electric and hybrid cars, with potential application in normal operation and the proximity of their main characteristics, such as mileage, price and service when traveling. The energy required to operate the electric stored in batteries are recharged using the power stations, which is also devoted part of the work. The thesis focuses on the design and calculation of power consumption for a defined route of four-wheel electric wheelchair. The conclusion of the thesis deals with the future development of hybrid and electric vehicles, and with the expected trends in the field of power electronics and motors and with the propagation of hybrid vehicles to the customers.

The Gallery of Brno Grand Prix
Sikora, Zbigniew ; Boleslavská, Yvona (referee) ; Žalmanová, Petra (advisor)
The main task of this thesis was to create an architectural study of The Gallery of Brno Grand Prix based on previous urban study from previous semester works. The proposal is focused on the iconic circuit’s former glory restoration, on providing new content for raceway complex and creating decent and presentable place for the presentation of the rich history of Czech and Czechoslovak motorsport. The result is a study of an object that meets these needs while respecting the historical and morphological values of the place. The building creates new themed attraction and creates the potential for further development of near circuit.

The engine unit of forestry harvestor
Petr, Tomáš ; Škopán, Miroslav (referee) ; Kašpárek, Jaroslav (advisor)
At the beginning of bachelor´s thesis is description of harvester and its main parts. Then research of four six – wheeled forestry harvesters was developed. Features of compared harvesters are similar to the task. The next point was theoretical part with equations needed for calculation of rolling and inertial resistances. Based on the theory an enumeration of powers of particular driving modes was done. Then performances for work devices of harvester were calculated. From the single values were determined total powers of machine, which were transparently organized into table and graph. Based on the maximal total power were chosen three appropriate engines. From the three was selected the most suitable one.

Aircraft windshield blowing: solution and design possibilities
Šamša, Petr ; Fišer, Jan (referee) ; Jícha, Miroslav (advisor)
My thesis is considering with aircraft windshield blowing for airplanes designed according to CS-23 regulation. The first part introduces the size of precipitation clearing area in connection with CS-23 regulation and report SAE AIR805C. Next chapter describes a few possible design solutions which can be potentially used for windshield precipitation. There are also other methods analysed in that part. There are not only the casual systems like windshield wipers but some more rare or new technologies too. It can be some fluid repellent surfaces or blowers in that category. The third part deals with jet blast system in detail. There will be a design calculation for airflow conditions which are important for the correct function. The last quarter of this thesis mentions the experiment what should compare the theoretical computations from the third part with the real values.
