Research Abstract

In rotor systems having a long-axis blade such as a turbine, zero and one modal diameter (k=0 and k=1) modes are well known with respect to blade-shaft coupled vibration.This study deal with the latter case that blades (k=1) are coupling with bending shaft vibration. In simulations and experiments, the coupled resonance wasconfirmed at the rotational speed which is |wb -ws|(where wb is blade natural frequency and ws is shaft natural frequency).
