Abstract

Aiming at the problem of the high on-line vibration of the nuclear power half-speed turbo-generator,this paper made a step-by-step analysis according to the vibration spectrum,off-line vibration test,electromagnetic interference verification,and natural frequency knock test.Finally a conclusion was made that the natural frequency of the sensor support setting is close to the four times harmonic wave of the generator operating frequency,resulting in sensor support setting resonance,which is the key reason of the high on-line vibration measurement.
- Vibration,
- Sensor support setting,
- Natural frequency,
- Resonance
