论文摘要
我们研究了机电谐波振荡器链作为能量收割机的性能，以从有限带宽的环境随机振动中提取功率，该振动是由有色噪声建模的。提出的设备是数值模拟的，其性能通过产生的净电力及其在将外部噪声供电的功率转换为电力方面的效率。我们的主要结果是，在流行的单个振荡器谐振器方面，谐波链的净电力和效率的净电力均具有巨大的性能。我们的数值发现是通过分析近似来解释的，与数字非常吻合。
We study the performance of an electromechanical harmonic oscillator chain as an energy harvester to extract power from finite-bandwidth ambient random vibrations, which are modelled by colored noise. The proposed device is numerically simulated and its performance assessed by means of the net electrical power generated and its efficiency in converting the external noise-supplied power into electrical power. Our main result is a much enhanced performance, both in the net electrical power delivered and in efficiency, of the harmonic chain with respect to the popular single oscillator resonator. Our numerical findings are explained by means of an analytical approximation, in excellent agreement with numerics.
