摘要
针对目前车辆振动能量回收率较低的问题,为探究路面振动能量俘获技术,笔者对基于压电效应的道路振动能量俘获系统进行了研究.设计并搭建了能量俘获模拟系统,并进行了测试.首先,基于PZT-5H系列压电陶瓷设计了压电振子,并对影响压电振子能量转化效率的振动模态及支撑方式进行分析及设计;然后,对整流电路、稳压电路及储能电路进行了分析,并基于集成芯片LTC3588-1 设计了外围电路,通过引脚选择3.3V的输出电压并将其输出的电能储存在超级电容中;最后,利用激振器搭建了道路振动能量俘获模拟系统对压电振子进行了测试.LED灯的模拟负载电路验证了该能量俘获系统的可行性;激振器载荷加载试验结果表明该能量俘获系统的能量转换效率约为0.5%.
Abstract
Aiming at the low recovery rate of vehicle vibration energy,in order to explore the technology of road vibration energy harvesting,the energy harvesting system of road vibration based on piezoelectric effect was studied..The simulation system of energy harvesting was designed and built,and the testing was conducted accordingly.Firstly,the piezoelectric transducer was designed based on the PZT-5H series piezoelectric ceramics,and the vibration mode and support method which affect the energy conversion efficiency of piezoelectric transducer were analyzed and designed.Then,the rectifier circuit,voltage regulator circuit and energy storage circuit were analyzed,and the peripheral circuit was designed based on the integrated chip LTC3588-1.The 3.3 V output voltage was selected through pins and the output energy was stored in a supercapacitor.Finally,the road vibration energy harvesting simulation system was built using an exciter and tested the piezoelectric transducer.The feasibility of the energy harvesting system was verified through the simulated load circuit of LED light.The results of vibration exciter loading test show that the energy conversion efficiency of the energy harvesting system is about 0.5%.
