Title:
METHOD TO DETECT VIBRATION NODES BETWEEN A SENSOR AND AN ACTUATOR IN A ROTATABLE COMPONENT
Document Type and Number:
WIPO Patent Application WO/2016/076985
Kind Code:
A8
Abstract:
A method of detecting a vibration node between a non-collocated sensor-actuator pair of a rotatable component includes applying an excitation signal to an actuator of the sensor actuator pair. The method also includes obtaining frequency response data from the sensor-actuator pair. The method further includes analyzing the frequency response data to ascertain a resonant frequency of the rotatable component. The method includes identifying a resonance/anti-resonance peak pair in the frequency response data for the non-collocated sensor-actuator pair. Furthermore, the method includes determining whether the vibration node is located between a sensor and the actuator of the non-collocated sensor-actuator pair based on the resonance/anti-resonance peak pair.
