摘要

根据振动学及电磁学理论，建立了采集器工作的物理模型，设计了一种平面弹簧式四永磁体结构振动能量采集装置，对拾振结构和换能结构进行了理论与仿真分析，讨论了采集器后续接口电路的整体设计方案，并对该电路进行了优化仿真，通过实验测试了该装置的性能，验证了其有效性和可靠性。实验结果表明，该采集装置接口电路输出电压可以在0.25s内上升到9V，此时，电压比较电路产生一个触发信号控制模拟开关导通，使设备正常工作，证明该采集器能可靠使用。

Abstract

A kind of planar spring with four permanent magnet structure of vibration energy collector is designed based on the vibration and electromagnetic theories. The vibration picking system and energy conversion system of the structure are analyzed through theory and simulation. The overall design of the subsequent interface circuit is discussed and the corresponding circuits are optimized by simulation. The performance of the device is tested by experiment to verify its validity and reliability. Experiment results show that the interface circuit output voltage can reach to 9V within 0.25s. Then, the voltage comparison circuit generates a trigger signal to turn on analog switch so that the devices can work normally，which verifies the reliability of the system.
