A research of dynamics of the model shrouded blade wheel in the IT is presented. Excitation of vibration of a rotating bladed wheel has been solved theoretically. The appliance developed for excitation of vibrations is described. Two solutions with permanent magnets and an electromagnet are discussed. Resonant vibration adjustment by frequency revolution tuning is discussed as well. Vibration and related phenomena brought about by an electromagnet excitation were measured by extended magneto-kinematics system VDS-UT designed and developed in the IT. This system is oriented to vibration measurements on turbine rotor blades in a long-term operation. The measurement set-up is described and results of rotating wheel vibration analysis are presented.
