Abstract: The requirement for wide operation range of steam turbine can cause, that the blades work close to resonant frequency. For decreasing of blade’s vibration there are placed damping elements in the blade shroud. These elements are calculated for dissipation of the vibration energy. The analytical method of blade and bladed disk modal analysis is introduced. The method enables to include blades both with and without damping elements in shroud. The mathematical model of the bladed disk is prepared for including damping effects in contact planes.
