Quality of The Track Geometry Progress
Peňázová, Gabriela ; Volejník, Miloslav (referee) ; Svoboda, Richard (advisor)
The bachelor’s thesis deals with the development of track geometry over the course of time. The first part describes current system of measuring and evaluating of track geometry. The second part uses the described system on the specified track section of the double-track line Hodonín-Rohatec. The measured data provided by SŽDC are evaluated and compared with the track maintenance work. For the chosen sections the exponential and linear functions for the development of longitudinal elevation were established and we judge the possibility of using them for the prediction of track quality development.

Analysis of railway behavior on vehicles effects
Peňázová, Gabriela ; Kala, Jiří (referee) ; Salajka, Vlastislav (advisor)
The master’s thesis deals with the possibilities of railway track modeling. The computational models were created in ANSYS Classic. Simplified 2D model represents a longitudal half of classic single track construction, 3D models represent classic single track construction and RHEDA 2000 slab track. Static and dynamic response of 2D model was compared with analytical solutions by Timoshenko and Fryba. Static and dynamic responses of 3D models were analyzed and compared.
