The Features of Resonance Stressscatter in Turbine Wheels with a Weak Connectivity of Blade Vibrations

Authors : A.I. Ermakov, A.V. Urlapkin and D.G. Fedorchenko

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.
