摘要

为拓宽振动压电能量收集装置工作频带宽度，提出一种新型两自由度分段线性能量收集结构，同时为便于未来对该装置进一步的关键参数优化与微小型设计，提出该结构的理论模型并给出解析解结果，通过对实验样机加工与实验平台搭建得到所提出装置发电性能实验结果。对比理论值与实验值表明，所提出装置在第一共振区间与第二共振区间的工作频带宽度分别为2.2Hz与4.5Hz，总频带宽度达到6.7Hz，与相对应两自由度线性系统比较，其拓宽效果达到4.78倍。在误差允许范围内，装置发电性能解析解结果与实验值基本保持一致，所提出装置能够有效拓宽发电工作频带宽度。

Abstract

A novel two-degree-of-freedom piecewise-linear piezoelectric energy harvester was proposed to achieve wide operation frequency bandwidth. The theoretical model was established and the analytical solutions were given for the further optimize design and microminiaturization fabricating of the proposed device. Through the prototype fabricating and the experiment platform building, the experiment results were obtained. The analytical results and experiment results showed that The operation frequency bandwidths of the proposed device in the first resonance region and in the second resonance region were 2.2Hz and 4.5Hz respectively, the total bandwidth was 6.7Hz, which reached as 4.78 times as the corresponding linear system. Within the margin of error, the analytical solutions were close to the experiment results, and the proposed device could extend the bandwidth of the operation frequency efficiently.
