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.
Analysis of acoustic and vibration parameters from rail transport
Turčíková, Hana ; Tomandl, Vladimír (referee) ; Smutný, Jaroslav (advisor)
This diploma thesis is focused on operational testing of selected railway lines with different structures of superstructure. For the measurement purposes suitable measuring sections in directional curves on the rail corridors were chosen and suitable measuring methodology was designed. Based on all the tests the dynamic and acoustic parameters of tested structures were determined. For the test evaluations suitable mathematic methods in both time and frequency zone was chosen. Part of my work is also to compare the parameters of the tested structures and to make recommendations for practise.
