"In the first part of the report the preparation and realization of the experiment on the model test wheel with beam blades having built-in wedge-shaped friction elements. The preparation considered the placement of strain-gauges on the wheel for a deformation measurement, installation of sensors for a friction element displacement observation and the electromagnet for an excitation of resonant vibration at different revolutions. The experiment realization includes both modal analysis of the wheel with and without the friction elements in steady state and analysis of blade vibration at selected revolutions in the range from 60 up to 2100 rpm. Besides the electromagnetic excitation the experiment with the permanent magnet excitation was performed. For evaluation of the friction element influence the comparison method was used when the vibrations of the wheel with the friction elements with the case of the wheel without friction elements at the same test conditions were compare"@en .
