摘要

一个应力偏压，圆顶，机电弯曲称为彩虹最近被开发。研究了基于压电复合材料的彩虹器件在远低于基频谐振模态频率范围内的位移特性。实验得到的场致位移与有限元模型预测的场致位移进行了比较。该模型低估了观测到的位移。实验观察到位移的低频松弛。

Electromechanical properties of Rainbow devices

A stress-biased, domed, electromechanical bender called a Rainbow was recently developed. Displacement characteristics for Rainbow devices based on piezoelectric PLZT compositions were studied in the frequency range far below the fundamental resonant mode frequency. Experimentally obtained field-induced displacements were compared with those predicted by a finite element model. The model underestimated the observed displacements. Low frequency relaxation of the displacements was observed experimentally.
