Paper is concerned with the steady state flexural vibrations of imperfect bladed circular disk by analytical and numerical solutions. Disk imperfection results from additional two groups of damping heads fixed on opposite ends of one diameter, which introduces point imperfections in mass, stiffness and nonlinear damping The main aim of this study is to investigate influence of friction damping among adding bladed heads on decrease of resonance amplitudes. Examples based on application of equivalent linearized damping show the properties of such dampers.
