Abstract: Response of the five-blade-bunch linked in the shroud by means viscous-elastic damping connections and excited by running harmonic forces is investigated. This type of excitation corresponds to the real excitation in the steam or gas turbine with different number of rotor and stator blades. After ascertaining of phase delay between neighbouring blades, the different dynamic properties of isolated and closed five-blade bunch are shown and analysed in this contribution. Recommendation how apply ascertained results for evaluation of experimentally gained data from dynamic measurements on bladed disk is added.
