| Abstract: | The present paper offers a method of balancing dynamically the flexible rotors with the technique of modal parameter identification. To take the errors of measurement data in the process of balancing into account, the maximum likelihood estimation is adopted. In order to demonstrate the validity of this method, some examples with computer analog are given and the measure to accelerate the convergency is proposed. The computation results show the effect of this method is highly satisfactory. |
