dc.description.abstract-translatedThis paper deals with vibration of a bladed disk containing internal friction dampers (FD). The disk is considered as a weakly coupled discrete cyclic structure where the blades are moreover mutually coupled by means of friction couplings. The global dynamics of the structure is studied. First, two limit cases are considered: unlocked FD and completely locked FD. Further, the behaviour of the structure is analysed with respect to time-dependent excitation (external force pulses). Different local behaviour is analysed along with discontinuity induced bifurcations like crossing-sliding and adding-sliding bifurcations. The stress is laid on the evaluation of dissipated power in FD per a defined time frame.en
