    摘要:

    提出了一种多自由度宽频带压电磁电复合式动能采集器,该动能采集器可以在多方向采集动能,有效地工作于较宽的频带,且可以同时以压电和磁电方式收集动能,大大提高了动能采集效率。介绍了复合式动能采集器的结构;分析和优化了采集器的拾振系统,从理论上验证了采集器的多自由度和宽频带的特性;介绍了磁电换能系统。研究结果表明,采集器在不同的工作频率下出现了两个振动峰值,验证了采集器的宽频带动能采集特性。通过实验测试进一步得出,与压电或磁电换能系统各自的输出性能相比,压电磁电复合式换能系统的总体输出性能有所提高。

    Abstract:

    The paper presents a hybrid piezoelectric and magnetoelectric vibration energy harvester with multiple degrees of freedom and broadband. The harvester can extract vibration energy on multiple directions and work in a wide frequency band effectively. It can greatly improve the efficiency of harvesting vibration energy with piezoelectric mechanism and magnetoelectric mechanism together. The paper introduces the structure of the hybrid vibration energy harvester. The vibration system is analyzed and optimized, and the characteristics of multiple degrees of freedom and broadband of the harvester are verified theoretically. And the paper also introduces the system of magnetoelectric transducer. The results show that under different operating frequencies, it appears two vibration peaks, which verifies the characteristic of broadband. Through experiment tests, compared with the output performance of piezoelectric transducer system or magneteoelectric transducer system respectively, the output performance of hybrid piezoelectric and magnetoelectric transducer system has greatly improvement.
