We study transmission of electric energy through an elastic plate by acoustic wave propagation and piezoelectric transducers. Our mechanics model consists of an elastic plate with finite piezoelectric patches on both sides of the plate. A theoretical analysis using the equations of elasticity and piezoelectricity is performed. Energy trapping that describes the confinement and localization of the vibration energy is examined.
我们通过声波传播和压电换能器研究电能在弹性板中的传输。我们的力学模型由一块在其两侧带有有限压电贴片的弹性板组成。利用弹性和压电方程进行了理论分析。研究了描述振动能量的限制和定位的能量俘获现象。
