抗磁悬浮能量采集器振动与输出特性分析
Output Characteristic and Vibration Characteristic Analysis of Micro-Vibration Energy Harvester Based on Diamagnetic Levitation
摘要
Abstract
On the basis of analyzing the nonlinear vibration characteristics of levitation permanent magnet in the dia-magnetic vibration energy harvester,we could analyze the infuences of structure parameters to the output characteris-tics of the induction coil. We used MATLAB to simulate nonlinear vibration characteristics of micro-vibration energy harvester and the finite element analysis software COMSOL to simulate the output characteristics of energy harvester. By changing the coil parameters,we found that when the coil volume was determined,the changes of output power were very small but the voltage increased quickly with the increasing of coil diameter. Therefore,the output voltage of the coil could be improved by reducing the diameter of the wire by micro machines. Finally,when the total vol-ume of the coil was about 6.4 mm3 ,wire diameter was 0.02 mm,coil number were 500,the voltage-peak reached a-bout 93.8 mV.关键词
