摘要
基于压电材料的能量采集装置具有响应速度快、电控性能好、无电磁干扰等优点.设计了一种圆柱形压电振子,工作模式为d33型的压电能量采集装置,并对其进行了有限元仿真分析,通过搭建实验平台对压电陶瓷进行了发电实验验证,结果显示随着频率和振幅的增加,电压幅值也增加.
The Energy harvester is a energy collection device based on piezoelectric material with a fast re- sponse, the good control performance, no electromagnetic interference and other advantages. The energy harvester with the d33 working mode for circular piezoelectric vibrator is designed and finite element simu- lation analysis is done by using the ANSYS. An experimental test bed is built to verify the power genera- tion of the piezoelectric material. The result shows that the voltage amplititude of the energy harvester is enhanced with the increase of the frequency and amplititude.
