Design of the axial dendritic suspension of steam turbine rotor blade

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
