The work presents analysis of vibrations of turbomachine blading with damages. 3D models and finite elements method are used. The influence of the different depth and locations of cracks on the natural frequencies, displacement forms and stress intensity is analyzed. The real turbomachine blading with damages is considerated. The validity of results obtained has been done by comparison with experimental data. The received results can be used at research of vibration stress localizations of turbomachine blading with damages.
