Dynamic analysis of track
Mojžíšek, Dominik ; Salajka, Vlastislav (referee) ; Plášek, Otto (advisor)
The diploma thesis deals with descriptions of vehicle - track dynamic interface. There are described basic analytical models of railway track. The numerical models are created by using finite element methods with moving load simulated axle of rail vehicle. The aim of thesis is to create the model which most accurately describes the dynamic phenomena in the track. The results from models are compared with data obtained by measuring in the track. Next aim of thesis is to determine dependency of rail cross-sectional characteristics on equivalent rail head wear and then on rail deflection.

Reconstruction of Ostrava-Kunčice - Ostrava-Vítkovice Track Section
Mojžíšek, Dominik ; Sobotka, Lukáš (referee) ; Plášek, Otto (advisor)
Traget of this bachelor thesis is to design a reconstruction of Ostrava-Kunčice – Ostrava-Vítkovice track section. It focuses on a design of modification of the track geometry parameters, design of an composition of the railway superstructure and substructure, design of station head in the railway station Ostrava-Vítkovice, design renewal of drainage, a construction procedure of works and a bill of quantities. Possibility of increasing the line speed was examined.
