| 中文摘要: |
| 介绍了一种利用压电叠堆激励管道内液体介质发生谐振产生正弦压力的发生装置.与其它正弦压力发生器相比,本装置压力源的激励方式新颖,工作频率较高,所产生的正弦压力波的幅值较大,失真度较小. |
| 英文摘要: |
| Theory of sinusoidal pressure produced by the resonance of the liquid in hydraulic pipe excited by piezoelectric ceramics is presented.Sinusoidal pressure with big amplitude and small distortion produced when the resonance occurred.Compared with other sinusoidal pressure generators,in high frequency,the amplitude of sinusoidal pressure produced by this device is the biggest.Furthermore,the pressure source is excited by a different way in this device. |
