叶片泵线谱振动有源控制

Active Control of Vibration with Line-Spectrum of the Blade Pump

叶片泵是典型的旋转类泵,其线谱振动控制是振动噪声控制领域的研究热点。以控制叶片泵低频特征线谱为目标,研究基于有源消振技术的低频特征线谱控制方法,建立叶片泵振动特性试验装置,通过试验检验有源振动控制措施对于叶片泵特征线谱的控制效果。

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.
