Title:
CONTACT VIBRATION DETECTION DEVICE, ROTATING MACHINE PROVIDED WITH SAME, AND CONTACT VIBRATION DETECTION METHOD
Document Type and Number:
WIPO Patent Application WO/2019/187517
Kind Code:
A1
Abstract:
This contact vibration detection device 100 is for detecting contact vibration resulting from the contact of a stopping part 13 with a rotating shaft 12. The contact vibration detection device 100 comprises a rotation waveform determination unit 101 for determining a rotation waveform for the rotating shaft 12 on the basis of the displacement of the rotating shaft 12 during rotation, a parameter variation detection unit 102 for detecting variation in parameters consisting of the root mean square and phase angle of the rotation waveform, and a contact vibration determination unit 103 for determining whether there has been contact vibration on the basis of whether there has been parameter variation.
