| 为实现对高频大振幅传感器的校准根据大振幅位移振动台的需求，研制了一种基于压电陶瓷的大振幅振动台。用PZT8材料的压电陶瓷片堆叠作为动元件，用功率放大器、电感箱和压电陶瓷片堆叠构成的LC谐振电路，对信号源输出信号进行功率和电压放大，驱动压电陶瓷堆叠振动。该振动台可以实现很小失真的振动，工作频率范围2 ~ 5 kHz，振幅最大可达到7 μm,失真度小于5%。 |
| 英文摘要: |
| A large amplitude vibrator is designed based on piezoelectric ceramic to perform calibration of large amplitude vibrators. The actuating element is made of PZT8 material. A power amplifier and a LC resonant circuit which composes of inductance and piezoelectric ceramic magnify input signals and drive the vibration of piezoelectric ceramic. Vibration frequency ranges from 2 kHz to 5 kHz, the maximum amplitude reaches 7 μm and the distortion is lower than 5%. |
