| 摘 要： | 建立了压电层合梁-板结构的压电-弹性动力学基本方程式，在给定压电层合梁-板结构形式和波传播方向的情况下，对基本方程式进行了简化；利用连续性条件和边界条件，建立了波传播的特征方程式，并对波动方程式进行求解；得到了前三阶频散关系曲线。通过实例数值计算，讨论了弹性层、压电层的厚度比与频散关系的影响，得出了SH波在压电层合梁-板结构中传播的基本特性。

| Abstract: | SH-wave propagation in piezoelectric-elastic layered beam-plate structures is investigated. The basic equations of dynamics of a piezoelectric-elastic layered beam-plate are established. The basic equations are simplified after the form of the layered piezoelectric-elastic beam-plate structure and the direction of wave propagation are given. The dispersion relations of wave propagation are derived by using the continuum conditions and the boundary conditions and solving the basic equations. Via numerical computing, the relationship among thickness of elastic layer, thickness of piezoelectric layers and dispersion relations is discussed. The characteristics of SH-wave propagation in piezoelectric-elastic layered beam-plate structures are obtained. |
