Title:
METHOD FOR DIAGNOSING ROTATION DEVICE BY MEANS OF ROTOR-BEARING-FOUNDATION MODEL
Document Type and Number:
WIPO Patent Application WO/2018/044034
Kind Code:
A1
Abstract:
The present invention provides a method for diagnosing a rotation device by means of a rotor-bearing-foundation model, the method characterized by utilizing the characteristics of a simulation rotor system. To this end, the present invention comprises the steps of: simulating a rotation device as a rotor system; forming a mathematical model for the rotor system; estimating the state of the rotation device by means of the mathematical model and a vibration measurement value of the rotation device; and diagnosing for abnormalities in the rotation device from the changes in an estimated value. Therefore, since a rotation device is diagnosed for abnormalities by means of forming a mathematical model for a rotor system, the present invention enables more accurate diagnosis of the rotation device.
