1. A repair announcement method for announcing a repair of a mechanical component, comprising:

  • measuring a frequency response characteristic of the mechanical component at an initial installation state of the mechanical component;

    determining a first frequency corresponding to a resonance point of the mechanical component according to measurement data at the initial installation state;

    measuring the frequency response characteristic of the mechanical component after a predetermined operating time elapses;

    determining a second frequency corresponding to a resonance point of the mechanical component according to measurement data after the predetermined operating time elapses; and

    issuing the repair announcement by judging that a timing of repairing the mechanical component corresponding to the resonance point has arrived when a deviation between the first frequency and the second frequency exceeds a predetermined allowable value.
