Balancing for a Flexible Rotor Considering the Vibration Mode : 2nd Report, Balancing in which Modal Influence Coefficients Contain Phase Angle Errors

抄録

The effectiveness of a modal-least squares balancing method is investigated with regard to a balancing of flexible rotors. The method combines features of both modal balancing and least squares balancing methods. Numerical simulations are carried out with influence coefficients which are assumed to have phase angle errors. The good balancing conditions that were obtained in the second balancing trial are also described.
