Design of the Gear Coupling for Railway Vehicle Application
Pelíšek, Vojtěch ; Řehák, Kamil (referee) ; Prokop, Aleš (advisor)
The aim of this work was to create a design of a gear coupling for railway vehicle application. The work presents a comprehensive view of this issue. First of all, a brief theoretical introduction to the issue is made. The practical part follows, where the design of the whole coupling and especially the newly designed solutions are described in detail. The strength analysis performed deal with the key components that are necessary to ensure safe operation. These analyses can be applied not only for this particular case, but also to gear couplings of different designs, because in principle these calculations do not differ much. In the last chapter, which deals with the dynamic model, all the theoretical assumptions are verified, especially the coupling movements and the applied loads. If the reader deals with the issue of gear couplings, not only in the railway industry, this work presents a comprehensive view of this component. The designed coupling and all performed simulations are really usable in operation.

Noise in rail transport
Maňák, František ; Prokop, Aleš (referee) ; Řehák, Kamil (advisor)
This bachelor's thesis is about the noise of the rail transport, this thesis is focused on the noise, that is generated by trains on the track. This thesis includes analysis of dominant noise sources from rail transport, factors affecting noise and noise measures, which minimize noise from the rail transport as effectively as possible. These measures can be divided into active and passive, each measure has its own advantages and disadvantages. The conclusion describes an evaluation of current trends and considers the future possible development of noise measures.

Conceptual design of dosing system for sand
Jíša, Martin ; Omasta, Milan (referee) ; Smejkal, David (advisor)
This bachelor thesis is focused on conceptual design of a dosing system for sand in railway use. At the beginning after the introduction into the problematics, there is adetailed research of competitive devices currently on the market followed by a detailed analysis of their functions. Summary of all requirements (functional and technological) is made. Mechanical design of the current doser and two new design alternations are made. Those alternations are chosen to be the optimal solution for the new doser.

Traumatic consequences of pedestrian - tram interaction and specifics in the case of child - pedestrians
Belková, Natália ; Jelen, Karel (advisor) ; Tlapáková, Eva (referee)
Title: Traumatic consequences of pedestrian-tram interaction and specifics in the case of child-pedestrians Objectives: The aim of the paper is to analyze the issue of pedestrian-tram traffic accidents in respect of injury consequences, based on available literary sources in accordance with the selection criteria. Special attention is paid to where such accidents involve children. The work is part of the grant ANALYSIS OF ACCIDENT EVENTS CHODEC TRAMVAJ. It aims to evaluate the occurrence, type and nature of injuries where collisions have taken place between pedestrians and trams. Methods: The thesis is produced on the basis of literary research. Due to the breadth of the interdisciplinary nature of the issue, literary sources were searched in the NCBI, Sciencedirect, Springerlink, Researchgate, PubMed databases. The first part of the thesis contains a theoretical introduction to the issue of tram transport and the definition of basic concepts, injuries of individual parts of the locomotor system and accident mechanisms in terms of biomechanics. The second part has a descriptive-analytical nature and contains an analysis of individual studies that deal with the health of a pedestrian/child accident, in relation to a tram. Results: At the end of the search, 64 studies met the selection criteria. Six...

Development of railroad sanding equipment
Matečka, Martin ; Růžička, Bronislav (referee) ; Omasta, Milan (advisor)
This master's thesis is engaged in development of new sanding units for a specific type of rail vehicle. Sanding in rail transport is application of most commonly silica sand into wheel-rail contact. Thanks to its reliability it is still the most widely used method for removing contaminants and improving adhesion in that contact. Sanding devices were developed in cooperation with corporation, which deals with production of rail transport equipment, among other things. The most important part of sanding device is sand dispenser. Dispensers were experimentally developed at the test station in the cooperating corporation. Dispensers were tested for utilization conditions on the locomotive of the train and conditions for trams and light rail vehicles. Furthermore, sand boxes have been designed for specific type of rail vehicle and new type of sand discharge tube, which directs sand directly into wheel-rail contact was designed too.
