研究了1-3型压电/聚合物复合材料在交变电场作用下的动态机电响应。压电复合材料包含在环氧树脂基体中的方形或圆形压电棒。利用1-3型压电复合材料的器件试样，进行了不同频率下的电阻抗和相位角的测量实验。利用三维有限元分析方法计算了其频率特性，并与实验结果进行了比较。然后详细讨论了1-3型压电复合材料中的动态机电场。
This paper studies the dynamic electromechanical response of 1-3 piezoelectric/polymer composites under alternating current (AC) electric fields. The piezocomposites contain square or circular piezoelectric rods in an epoxy matrix. Experiments were conducted to measure the electrical impedance and phase angle at various frequencies, using the device specimen of the 1-3 piezocomposites. Three dimensional finite element analysis was also employed to calculate the frequency characteristics, and a comparison is made between simulation and experiment. The dynamic electromechanical fields in the 1-3 piezocomposites are then discussed in detail.
