Description	Computational model of blade couple damped by the direct friction contact or by inserted friction element is numerically analyzed. System is excited by a harmonic external force with frequency close to the lowest eigenfrequency in the regime of sweep excitation. Response curves show the influence of torsion stiffness, type of friction characteristic etc. on the response curves of all masses. The main goal of this analysis is to elaborate the basic background for reduction of undesirable vibrations of blades and complete results of measurements on experimental model of turbine disk in laboratory IT ASCR.
