| 摘 要： | 基于一阶剪切变形理论和压电方程，推导了压电层舍板本构方程，得到一个双程压电-机械耦合的有限元模型，它可以对具有任意分布的表面粘贴式或嵌入式压电传感器和驱动器的复合材料层合板的机电响应进行分析。所得算例的计算结果与文献中的实验结果或ANSYS分析结果非常吻合，也显示了在压电传感器有信号输出时，单程压电-机械耦合的有限元模型所存在的误差。

| Abstract: | The constitutive equations of the piezoelectric laminated plate are formulated based on the first order shear theory and the piezoelectric equation. A two-way piezoelectric-mechanic coupled finite element model is obtained. It can be used to analyze mechanic-electric responses of composite laminated plates with arbitrary distributed piezoelectric sensors and actuators. The computed results agree well with the results of experimental in literature and ANSYS analysis. It also shows that the one-way piezoelectric-mechanic coupled finite element model exists the faults when sensors have signal outputs. |
