A simple network representation is given for a stack of thin, homogeneous piezoelectric plates, executing a single thickness mode of motion. All plates may differ in thickness and material properties, including dielectric loss, ohmic conductivity, and viscous loss. Each plate is driven by a thickness-directed electric field, and all stack elements are connected electrically in series. Functionally gradient single plates and composites are readily modeled by the network, to a desired precision, using a sequence of circuit elements representing stepwise variations in material properties and layer thicknesses. Simulations of RAINBOW (Reduced And Internally Biased Oxide Wafer) ceramics are given.
给出了一叠薄的、均匀的压电板的简单网络表示，这些压电板执行单一厚度运动模式。所有板的厚度和材料特性可能不同，包括介电损耗、欧姆电导率和粘性损耗。每个板由厚度方向的电场驱动，并且所有堆叠元件串联电连接。功能梯度单板和复合材料可以通过该网络，使用表示材料特性和层厚度逐步变化的一系列电路元件，以所需的精度轻松建模。给出了RAINBOW（减少和内部偏置氧化晶片）陶瓷的模拟结果。
