Description	Regarding steam turbine blade vibrations, damping of blades as well as whole bladed disk vibrations are one of the most important parameters in terms of steam turbine operation. Values of the damping parameters depend on properties of material used for blades and disc as well as on geometric parameters of blade shroud contact areas with friction elements. The in-house made software enables fast parametric optimization using a multi-criteria function, for example angle of contact planes or mass of friction elements. The real bladed disk was excited in vakuum machine to provide material and construction damping. The measured modal properties and damping parameters identification are used for model correction as well as for detailed meshed model in commercial software.
