Abstract:
The control on vibraiton with line spectrum of the blade pump, which is a typical rotate pump, has become the research hotspot in the field of vibration and noise control. On the demand of reducing the periodic line spectrum vibration of the blade pump, this paper studied the method for the line spectrum vibration and noise reduction based on the active vibration control technology. The facility for the vibration test of the blade pump is built to study the characteristics of the periodic line spectrum. Then the line spectrum reduction performance of the approach applying on the test blade pump was verified by the experiment.
