Continuous welded rail in tight curves
Peřinová, Kateřina ; Szabó, Petr (referee) ; Plášek, Otto (advisor)
The diploma thesis deals with the curve radius influence on lateral stability of continuous welded rail. It is presented the overview of present state of knowledge in the field of stability of continuous welded rail. In practical part is created the model of a track section. The influence of some parameters on loss of stability of CWR was studied. The results it are compare with the analytic analysis.

Nonlinear analysis of continuous welded rail in curves of small radius
Murínová, Klára ; Szabó, Petr (referee) ; Plášek, Otto (advisor)
The diploma thesis examines the influence of curve radius on continuous welded rail stability in a small radius curve. Attention is paid to curves with a radius less than 300 m. The first part of the thesis summarises the theory of continuous welded track and influence of track parameters on track stability. The second part of the thesis deals with constructing of the numerical model of a curved track with the observed behaviour of track under thermal loading with positive and negative temperature values. The variable values in the model are rail shapes and different radius. In the end, the shape of the track lateral deflection as a function of temperature are evaluated.
