摘要
该文介绍了压电发电获取振动能的现状,近年来,人们对绿色能源的需求越来越大,利用压电发电获取环境中振动能成为研究焦点。阐述了压电发电基本原理,压电发电是利用了压电材料的正压电效应。设计测试系统实地测试了路基振动波形并探讨了在实验室中复现所测振动波形的方法。
Introduced the present situation of piezoelectric power generation from vibration, in recent years, as more and more green energy is demanded, using piezoelectric material to harvest vibration energy from environment become the focus of study. Introduced the basic principle of piezoelectric power generation, piezoelectric power generation is realized by using the piezoelectric material＇s piezoelectric effect. Designed test system and test the roadbed vibration waveform ,discussed a way to re- produce the vibration wave in the laboratory.
