A new methodology is proposed to measure the dielectric constant and loss of a piezoelectric at the resonance frequency range based on the burst excitation method. Using a k31 type soft PZT rectangular specimen, we investigated the ‘force’ and ‘voltage’ factors carefully under the short- and open-circuit conditions of the burst method, in terms of the ratio of the ring-down current and voltage with the plate end vibration velocity and the displacement, and their phase lags. We provide the obtained material properties, including loss parameters, in particular, dielectric properties at the resonance frequency range. This article is protected by copyright.

确定谐振频率范围内压电材料介电常数的新方法

提出了一种基于突发激励法测量谐振频率范围内压电体介电常数和损耗的新方法。使用 k31 型软 PZT 矩形试样，我们仔细研究了在突发方法的短路和开路条件下的“力”和“电压”因素，根据衰荡电流和电压与板端振动速度和位移，以及它们的相位滞后。我们提供获得的材料特性，包括损耗参数，特别是谐振频率范围内的介电特性。本文受版权保护。版权所有。
