Step 10：It takes awayAccording to the P being calculated in plane 11Aggravating radius r1Upper increase correction mass,
The vibration signal of A points and B points is measured under the same balancing speed V, theoretically, vibration should be zero, but due to many reasons,
Rotor-support-foundation system still can have unbalance residual content, and vibration at this time is referred to as residual oscillation.If residual oscillation is larger,
Need rule of thumb the position to correction mass and size be modified, or re-start dynamic balancing.If it find that equilibrated
After increasing test mass in journey, less, i.e. effect vector very little should change test mass at this time for the vibration variation at measuring point A and the places measuring point B
Size or orientation re-start test, and otherwise required influence coefficient poor quality, subsequent balancing work effect are poor.
Data when each dynamic balancing are preferably retained, and can quickly inquire the influence system of each balancing plane of rotor-support-foundation system in this way
Number, once imbalance fault occurs once again for rotor-support-foundation system, can save a large amount of time and expense, flat into action to it

Radius is r2, phase angle θ2, frequency converter is adjusted at balancing speed V, obtains the vibration signal of measuring point A and measuring point BWith
Increased test mass Q2With size and orientation, it is denoted as vector
Wherein：Aggravate radius r2；Phase angle θ2；I is imaginary number；E is natural logrithm；
Step 7：Calculate the influence coefficient of measuring point ACoefficient is influenced with measuring point B
Wherein：WithIndicate that the balancing plane 2 for being balanced rotor increases test mass respectivelyAfterwards, measuring point A and measuring point B
Vibration variable quantity, be effect vector；
Step 8：Calculate the correction mass P of measuring point A and measuring point B1And P2；
Step 9：The test mass of rotor will be balancedRemove, balancing plane 1 and balancing plane 2 are aggravating radius r respectively1、r2With
Phase calibration θ1、θ2Place increases correction mass P1And P2。
