3.1 Separation ratio - refers to the interference ratio of the two correction planes A and B for a given rotor. IAB and IBA are defined as follows. IAB=UABUBB×100% (1) IBA=UBAUAA×100% (2) Where. UAB, UBB--- respectively indicate that after adding the specified unbalance amount to the correction plane B, the A and B planes are not Balance amount indication value; UBA, UAA--- respectively indicate that after adding the specified unbalance amount to the correction plane A, the B and A faces are not Balance amount indication value; IAB---B faces the separation ratio of the A side; IBA---A faces the separation ratio of the B side. 3.2 Minimum reachable residual unbalance (emar)—The minimum amount of unbalance that the balancer can achieve. Yes A performance metric that measures the balance of the machine's highest balance. The unit of measurement is g·mm/kg. 3.3 Permissible residual unbalanced mass (me)---Check the remaining unevenness of the rotor per calibration plane test Measured, the unit of measure is g.

4 Overview

The working principle of the balancing machine is realized according to the theory of rotating rigid body dynamic balance, which is generally determined by the electromechanical conversion system.
