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.

The analysis of the dynamic and acoustic parameters of the superstructure construction
Bačík, Jakub ; Tomandl, Vladimír (referee) ; Smutný, Jaroslav (advisor)
This diploma thesis is focused on operational testing of selected railway lines with different structures of railway superstructure. For the purposes of measuring were chosen suitable measuring sections on the rail corridor and was designed suitable measuring methodology. Dynamic and acoustic parameters of tested structures were determined on the basis of all tests, which were performed. Suitable mathematic method was chosen for evaluation of tests in time and frequency zone. Part of my work is also compare parameters of the tested structures and recommendations for practice.
