Abstract
The parameter identification method in flexible rotor dynamic balancing by using the model analysis technology has been presented.This method needs only run-up once instead adding the test mass
regarding the mass of dynamic unbalancing as the paramenters of rotor shafting system's modal parameter
and according to the vibration responds
the n-step modal unbalancing can be determined by using the model analysis technology.A vast amount of verification tests shows that this method is effective and feasible.
