| 摘要 |
The proposed piezoelectric accelerometer contains a detecting element, two main electrodes, two additional electrodes, and two matching voltage amplifiers. The detecting element is designed as a piezoceramic cylinder with radial polarization. The main electrodes are arranged at the end surfaces of the detecting element. The additional electrodes are arranged at the inside and the outside surfaces of the detecting element. One of the main electrodes is connected to the input of the main amplifier. The second main electrode is connected to the output of the additional amplifier. The additional electrode that is arranged at the outside surface of the detecting element is connected to the input of the additional amplifier. The additional electrode that is arranged at the inside surface of the detecting element is connected to the common point of the circuit of the accelerometer.
