Introduction On account of the design and construction factors, coupled with uneven material and manufacturing installation error and other reasons, the entire actual rotor center inertia principal axis more or less deviated from its rotation axis.
As a typical flexible rotor shaft drive system components has been widely used, however，its dynamic balancing technology has also been plagued by engineering and technical personnel [2].
The balance of the flexible rotor is balanced in a certain speed range in engineering, in order to eliminate the n order flexural mode of rotor，usually the rotor is driven in turn to the corresponding critical speed for the rotor dynamic balance detection and correction.
