    • An imbalance correction method for correcting the imbalance of a rotor measures the vibration state of the rotor before temporary correction and the vibration state of the rotor after the temporary correction in a plurality of rotational speeds in order to make vibration values below the standard. An aggregation range of the tips of correction vectors for obtaining a vibration value which satisfies a vibration standard is calculated from vibration vectors in the rotational speeds. A real correction vector is selected from correction vectors having the tips in a region in which the aggregation ranges calculated for each of the rotational speeds overlap one another among a plurality of the correction vectors. A real correction amount and a real correction phase are set based on the real correction vector. The imbalance of the rotor is corrected based on the real correction amount and the real correction phase.
    • 用于校正转子不平衡的不平衡校正方法在暂时校正之后测量转子的振动状态和在多个转速中的临时校正之后的转子的振动状态,以使振动值低于标准。 根据旋转速度的振动矢量计算用于获得满足振动标准的振动值的校正矢量的前端的聚集范围。 从在多个校正矢量中的每个旋转速度计算的聚合范围彼此重叠的区域中具有尖端的校正矢量中选择实际校正矢量。 基于实际校正矢量来设定实际的校正量和实际校正相位。 基于实际校正量和实际校正相位来校正转子的不平衡。
