本文提出了通过测量压电陶瓷常用振动模基频附近的等效电路及其低频导纳(或阻抗)以获得压电陶瓷复数电弹常数的新的简便方法,此种方法比前人提出的方法简单且它的物理意义更加明确。
In this paper, a new and simple method to obtain the complex elastic constant of a piezoelectric ceramic by measuring the equivalent circuit near the fundamental frequency of the common mode of the piezoelectric ceramic and its low-frequency admittance (or impedance) is proposed. Compared with the proposed method The method is simple and its physical meaning is clearer.
