    Abstract: Forced vibrations of rotor wheels with nonidentical blades and a weak connectivity of vibrations are considered in the study. It is shown that in some frequencyranges such wheels lose the maincharacteristics peculiar to systems with a small deviation from rotation symmetry. It leads to a qualitative modification of character of their vibrations caused byinfluence of exciting harmonics. The mechanism of a resonance stressscatter in them becomes different.
