Abstract
Exciters vibrate blades of a disk of a blisk, using excitation signals of a traveling wave or a backward wave in which a phase is sequentially shifted in a traveling direction or a delay direction. A laser vibrometer outputs a laser beam for detecting a vibration of each of the blades and receives a reflected beam from a target irradiated with the laser beam. An optical path changer is arranged on an optical path of the laser beam and changes an optical path of the laser beam and the reflected beam based on a vibration detection position of a blade designated as an irradiation target for the laser beam from among the blades. A controller detects a vibration response to excitation of the respective blades, from the laser beam and the reflected beam corresponding to the respective blades being excited by the respective exciters.
