To Dvur Kralove by train - Transfer Terminal in Dvur Kralove nad Labem
Hudečková, Kristína ; Růžička, Tomáš (referee) ; Ponešová, Barbora (advisor)
The terminal represents joining two things – an internal and an external – a city and a surroundings. The intetion of my bachelor thesis is to connect fluently a main hiking trail from a center of city with a bus service and train transport. To make this connection as natural as possible, the proposal of terminal is based on a mass concentration in a point of joint and gradual diffusion towards the the city and the surroundings. The terminal is designed as a longitudinal structure with a one communication in the middle of the layout. The space of terminal is defined by twenty steel frames arranged one behind the other in the direction of the axis of connection between train track and hiking trail from the center of the city. The steel frame becomes the dominant element of the terminal. Different closing of sections between particular frames creates spaces of different characters and a different rate of permeability.

Potenciál města Zlína z hlediska cyklodopravy
Mizerová, Daniela
The dissertation deals with the bicycle as a means of transport in a specific environment in Zlín, a town located in the valley. The backbone cycle track runs along the river Drevnice and it is connected to the city route. Both the cycle track and the city route provide two basic functions -- transport and recreation. The user considers the flexibility and the safety when selecting round bike as a means of transport. It means the system must be integrated and it must be led through the space without collisions with other modes of transport. The bike must be secured at the place of its storage which is provided by the safety stands in Zlin. The recreation potential of the system can be increased by connecting to the bike path which runs along the Bata Canal and linking them with the interesting tourist targets around the city. Good awareness not only about tourist destinations but also about the overview of the entire network of cycle paths and lanes is ensured by Cyklo Zlín and it increases people's interest in issues of cycling.

LED bicycle lights
Čmelík, Matouš ; Patočka, Miroslav (referee) ; Huták, Petr (advisor)
In semester thesis i project bicycle lighting using LEDs that are powered from the alternator. The LEDs are powered also from battery, that is recharged while driving and when you stop it enable uninterrupted lighting. The concept is designed so that the final price is as low as possible. All things is designed to insert to the existing bicycle lightint on Eska or Favorit bicycle. The use of inverters ensures high efficienty of the whole concept. Using LEDs compare to standart solutions with bulbs is more efficienty to.

Design of Experimental Stand for the Study of Railway Vehicles Sanding
Galas, Radovan ; Hruška, Marek (referee) ; Šperka, Petr (advisor)
Presented master’s thesis describes the design and the implementation of an experimental device used for the study of tribological aspects of wheel-rail contact. In this work, the reader will first learn the fundamentals such as adhesion, slip, traction curve, etc. Subsequently, the work is describing devices that are used for the study of wheel-rail contact around the world. This section is followed by the author proposed solution. The result is a twin disc device in the scale of 1:3. The device allows determining traction characteristics for different environmental conditions (presence of water, sand and oil in contact for different temperatures) and various operating parameters (contact pressure and speed). A part of this work are also the validation experiments and complete design documentation.

Anylytical solver for strength calculation of railway axles
Fišer, Petr ; Náhlík, Luboš (referee) ; Vaverka, Michal (advisor)
This master thesis deals with wheel set axles of rail vehicles, their design and methods of implementation stress analysis. In this work, I created a powered locomotive wheel set: axle and wheel. For the purpose of the design department of the Bonatrans Group a.s. company I developed an analytical solver, which allows creating stress analysis, which will be used for verifying finished design and in addition it allows printing of stress analysis as report for the railway´s offices. Next step was a stress analysis of this design of axle in this analytical solver.

Analysis of potential active damping for vehicles
Svoboda, Jakub ; Houška, Pavel (referee) ; Hadaš, Zdeněk (advisor)
Diploma thesis deals with the issue of active and semi-active damping and its possible applications in the context of vehicles. The beginning of the document is focused on the actual state, major applications and patents in the field. As each of the individual ways of usage is relatively specific, the next part is aimed particularly at the damping unit of bicycle. Given the choice, real measurements and simulations were made in order to verify the applicability of such a device in practice.

Gearbox for portable power generator
Kolka, Roman ; Hubáček,, Tomáš (referee) ; Bradáč, František (advisor)
The submitted project deals with a complete design of a gearbox of a portable ground power generator designed for preflight preparation of helicopters. The gearbox has been designed to meet given specifications, which are based on required electrical parameters of the entire power unit and with regards to parameters of driving turbine engine. The introductory section deals with a kinematical design of transmission gears with regards to required parameters and design constraints. The kinematical design determines whole concept and resulting form of the gearbox. Next part deals with optimization of gearing, the design of wheel bearing, and design of oil system. The implementation part of the project consists in the engineering design of the gearbox, which was made in 3D environment Pro/Engineer. The design is reviewed and first operational results of manufactured and tested gearbox are discussed in the concluding section of this work.
