Assessment of Geometry Parameters of Track with Under Sleeper Pads
Škovranová, Michaela ; Volejník, Miloslav (referee) ; Hruzíková, Miroslava (advisor)
The diploma thesis applies to under sleeper pads. It researches thein using and benefits in foreign railvway authorities. Further it assesses track geometrical parameters in the trial track section with under sleeper pads in track Havlíčkův Brod - Okrouhlice and in the railway station Planá nad Lužnicí. There were evaluated measurements of vertical alingnment rails by precise leveling and deviations of track geometrical parameters measured by track meusuring car in the diploma thesis.There is expressed an conclusion about the impact of under sleeper pads on track geometric data in the thesis.
Modernization of Brno - Přerov railway line in Vyškov area for speed 200 km/h
Hašek, Jan ; Rotschein, Petr (referee) ; Plášek, Otto (advisor)
The objective of this master´s thesis is a design of modernization of railway line no. 300 Brno – Přerov in Vyškov area and its vicinity for speed 200 km/h. The track section is located between railway station Luleč and Ivanovice na Hané. The track is designed in two variants. The first variant is proposed keeping railway line through Vyškov railway station including necessary modification of the railway station. The second variant suggests keeping track outside Vyškov and a connection with the railway station by bridging is designed.
Classification and evaluation of rail wear
Nohel, Rostislav ; Frýza, Josef (referee) ; Galas, Radovan (advisor)
This bachelor’s thesis is focused on the wear of rails. In this thesis, the reader will be firstly introduced to the fundamentals such as nomenclature of wheel and rail, adhesion, adhesion coefficient, contact area, slip, traction characteristic and wear. Subsequently, the fundamental types of material wear (adhesive, abrasive and fatigue) will be explained, which occur in the wheel-rail contact. In the next part, the individual rail defects are analysed with respect to locations. The output of the bachelor’s thesis is overview and description of the most common rail defects which are usually caused by fatigue wear.
Locking device for sliding roofing of the swimming pool
Sedláček, Jan ; Hort, Filip (referee) ; Brandejs, Jan (advisor)
In first part, this bachelor thesis tries to summary possibilities of covering and roofing of swimming pool. It deals in detail with the most expanded type of swimming pool roofing – the sliding roofing. The analysis of roofing efficiency has been performed and the primary positivities of this type of roofing have been founded. The next section describes constituent elements of sliding roofing. The second part of bachelor thesis focuses on design of locking device for sliding roofing of the swimming pool. First, the proposal of solutions was done. The proposal is based on two solutions. The first proposal is based on the idea of railroad conduction in all segments, the second proposal suggest the railrod conduction only for the biggest segment, the other segments wheel on the floor. For the design was chosen second proposal, created a 3D model and drawn the assembly drawing.

Work content proposal of crane runway girder, travelling wheel, rail and in calculators part is proposal of parts of traveling crab like the drum, guide and balancing pulley, cable, hook, wheels, whels bearing, travelling wheel, drive of traveling crab. In work is assembly drawing and production drawing of drum.
Bludov - Hanusovice Railway Track Reconstruction (section between km 56.165 - km 59.105) Including Track Laying Technology
Hlavová, Vendula ; Korkeš, Ondřej (referee) ; Říha, Tomáš (advisor)
The bachelor thesis deals editing track geometry parameters and design appropriate track railway superstructure in a section of railway Bludov – Hanušovice. The design should be considered primarily on existing objects as culverts, railway crossing, railway stops, and bridges. Thesis includes restoration of drainage, track laying technology and efforts to incease the track speed.
Vsetin - Velke Karlovice Railway Track Refurbishment (section between km 2.725 - 6.000 km) Including Track Laying Technology
Klar, Vít ; Hoza, Miroslav (referee) ; Říha, Tomáš (advisor)
This thesis deals with the design of track geometry parameters and the reconstruction of the selected section of Vsetín – Velké Karlovice railway track’s superstructure. This reconstruction expands to further include the connection track to the Bečva branch. This proposal has been designed with the following objects in mind: railway stops Ústí u Vsetína and Janová, railway crossings, bridges, culverts, etc. Finally, this proposal addresses the restoration of drainage along the tracks and track laying technology. It should be noted, that all proposed adjustments are designed according to current regulations and legislation.
Vsetin - Velke Karlovice Railway Track Refurbishment (section between km 17,000 - 19,950 km) Including Track Laying Technology
Kulich, Pavel ; Pokorný, Ondřej (referee) ; Říha, Tomáš (advisor)

The design should be considered primarily on existing objects such as railway crossings, culverts, railway stops, bridges , etc. Thesis includes restoration of drainage and track laying technology. It should be noted, that all proposed adjustments are designed according to current regulations and legislation.
Monitoring of Quality of Track Geometry Parameters in Sections with Under Sleeper Pads
Grygar, Zdeněk ; Trejtnar, Radek (referee) ; Plášek, Otto (advisor)
The thesis is dedicated to the evaluation of quality of geometrical parameters of track in the section with under sleeps pads and comparability of the results of levelling and results of track recording car. The thesis summarizes results of levelling and results of track recording car in both Havlíčkův Brod - Okrouhlice test section and Planá nad Lužnicí railway station and their evaluations.
MEASUREMENT OF DYNAMIC PARAMETERS OF TRACK GRID
Podolník, Adam ; Tomandl, Vladimír (referee) ; Smutný, Jaroslav (advisor)
Coupled with theory analyses, various static and dynamic tests carrying out in laboratory or directly on site serve as a basis for selection and comparison of particular rail superstructure parts. It should be noted that the theoretical analysis of the application of mathematical modeling is often based on highly idealized assumptions. The purpose of this bachelor thesis is the experimental analysis of dynamic effects of selected flexible fastening structures without baseplates. Forces induced by the passage of trains have been simulated on a specially prepared samples using inertial exciter. Additional measurements of the dynamic response of structures to shock induced by a modal hammer were also performed. Measurements were performed in the laboratory of ÚPKO and ÚŽKS and in situ.
