Design of the axial dendritic suspension of steam turbine rotor blade
Vrbka, Dušan ; Majer, Zdeněk (referee) ; Dušek, Daniel (advisor)
This master thesis deals with axial dendritic suspension of steam turbine rotor blade. The initial shape of the suspension was design on the basis of available data. There was performed stress-strain analysis of this shape and most dangerous spots were picked. There were made several geometrical changes of the shape of suspension. Their affection on stress-strain responding of the suspension was examined. The best shape was chosen which was used to perform analysis of infinite life according to ASME code and due to loading low cycle fatigue analysis. According to results of low cycle fatigue analysis the maximum loading was established. At the end of this work the further steps were suggested.

Loading of the crane-runway girder
Vrbka, Dušan ; Fuis, Vladimír (referee) ; Suchánek, Miroslav (advisor)
The main purpose of this bachelor project is to solve Loading of the crane-runway girder. First of all, we located the possible dangerous places where we solved the running of Shear and moment diagrams which depends on distance of loading forces p from the beginning of the crane-runway. For the mathematic solutions, we used specialized software MAPLE. The main advantage of this software is the ability of the analytic analysis. We introduced the method of the solving the crane-runway girder on three supports. The final part shows the main results and highlights the most strained parts with suggestions for decrease loading level of strained parts.
