Abstract:
A rotating machine abnormality detection device and a rotating machine abnormality detection method according to the present invention are designed to detect an abnormality in a rotating machine including a rotary member rotatable about a predetermined axis, and detect an initial abnormality in the rotating machine based on first measurement data obtained by measuring a vibration in an ultrasonic wave band caused by the rotary member. A rotating machine according to the present invention includes the rotating machine abnormality detection device.
