基于颤动的精力 harvester 是实质上在一个有限频率范围工作的一个共鸣器。增加工作频率范围是一个挑战性的问题。这份报纸为提高经由内部回声收获的精力揭示新奇可能性。内部回声精力 harvester 被建议。刺激连续地作为 Gaussian 白噪音,一个秒顺序过滤器定义的有颜色的噪音,狭窄乐队的噪音,和指数地相关的噪音被假定。相应平均 root-mean-square 产量电压被计算。数字结果证明内部回声增加操作带宽和产量电压。
A vibration-based energy harvester is essentially a resonator working in a limited frequency range.To increase the working frequency range is a challenging problem.This paper reveals a novel possibility for enhancing energy harvesting via internal resonance.An internal resonance energy harvester is proposed.The excitation is successively assumed as the Gaussian white noise,the colored noise defined by a second-order filter,the narrow-band noise,and exponentially correlated noise.The corresponding averaged root-meansquare output voltages are computed.Numerical results demonstrate that the internal resonance increases the operating bandwidth and the output voltage.
