UNBALANCE CORRECTION METHOD FOR ROTATING BODY AND UNBALANCE CORRECTION AMOUNT ARITHMETIC UNIT

摘要

PROBLEM TO BE SOLVED: To provide an unbalance correction method for a rotating body, in which vibration values in a determination rotational speed range are made to be equal to or less than a standard.;SOLUTION: In an unbalance correction method, vibration states of a rotating body before and after temporary correction are measured in a plurality of rotational speeds in a determination rotational speed range by executing an initial vibration measurement step S1, a temporary correction step S2, an unbalance state confirmation step S3, and a correction vector aggregation range arithmetic stage S4, and the aggregation range of the tip of a correction vector of which vibration value satisfies a vibration standard is calculated for each rotational speed from the vibration vector at each rotational speed. Then, in a proper correction amount setting step S5, a main correction vector is selected from the correction vectors having tips in a region where the aggregation ranges of the rotational speeds overlap and a correction amount and a correction phase are set based on the main correction vector, thereby performing unbalance correction of the rotating body in an unbalance correction step S6 based on the correction amount and the correction phase.;COPYRIGHT: (C)2012,JPO&INPIT
