单摆-电磁式振动能量收集器设计及实验
Design and Experiment of a Single Pendulum-electromagnetic Vibration Energy Harvester
摘要
Abstract
Vibration energy collector is a green energy creation technology,which continuously"power"the system microelectronics by collecting the vibration energy of the engineering system and converting it into electrical energy.Based on the principle of electromagnetic induction,a combined single pendulum-electromagnetic vibration energy harvester is designed,and finite element simulation analysis of the induction characteristics and the influencing factors of the induction characteristics are carried out with COMSOL platform,and output performance experiments are conducted.The results show that the combined single pendulum-electromagnetic vibration energy harvester consisting of sleeve,rotor,pendant,magnet,coil and rope has a simple structure,light mass of about 200 g,small size about 30 cm3,with a natural frequency between 70 and 80 Hz.At a vibration frequency of 20 Hz and a small amplitude of 8 mm,the output voltage of the collector is 240 mV.关键词
