摘要：
The formula is derived for calculating correction weights from motion equations of unsymmetrical rotor bearing system. Two trial weights are required in two trial operations for each balancing plane, and forward precession of trial responses are used to calculate the correction weights. Comparative experiments between this method and the conventional method are carried out on the test bench. Moreover, this method was used to balance a 600 MW generator bearing system, it decreased the balancing time and improved the balance accuracy. This method has been proved valid for balancing unsymmetrical rotor bearing system.
