Pisarenko Institute for Problems of Strength of the National Academy of Sciences of Ukraine popup.description2 The objects of investigations are forced vibrations of the airfoil of the compressor blade with a fatigue crack. The purpose of the work is to study the influence of a fatigue crack on the parameters of forced bending vibrations of the airfoil of the compressor blade and to determine the vibrodiagnostic parameters of its presence, taking into account the parameters of vibrations excitation and energy dissipation. Research methods are numerical. Using the developed FE models and methods of investigation the regularities of the influence of the local fatigue crack on the vibrodiagnostic parameters of its presence in the blades have been established, taking into account the parameters of vibration excitation and energy dissipation.
