<p>PROBLEM TO BE SOLVED: To provide an unbalance measuring device that can reduce procedures for measuring unbalance on an arbitrary balancing plane of a test object irrespective of a size of the unbalance measuring device.SOLUTION: An unbalance measuring device 1 includes: a vibrating frame 6; a vibration detector 7 for detecting vibration caused at the vibrating frame 6; a vibration exciter 9 attached to the vibrating frame 6; and a controller 10. The controller 10 calculates each influence coefficient on balancing planes P1 and P2 on the basis of: vibration detected by the vibration detector 7 at the time of moving the vibration exciter in a state where a rotor 2 of a test object 3 set to the vibrating frame 6 is stationary; a positional relationship between the balancing planes P1 and P2 at the test object 3 and the vibration exciter 9; and known unbalance. The controller 10 measures unbalance of the test object 3 on the balancing planes P1 and P2 on the basis of: data for the vibration detected by the vibration detector 7 at the time of rotating the rotor 2 in a state where the movement of the vibration exciter 9 stops; and the calculated influence coefficients.</p> |
