摘要为提高单频压电振动俘能器的能量转换效率和工作频带，结合压电和电磁能量转换机制，提出了一种新的混合俘能器系统。该系统由PZT悬臂梁、弹性悬挂磁铁块、粘附于悬臂梁末端磁铁块及谐振器等组成，引入谐振器及磁铁可实现增加系统模态数量和非线性。基于此混合振动俘能器建立了改进型连续体机电耦合解析模型，并由龙格-库塔算法进行了求解。在此基础上，研制了振动俘能器原理样机，并搭建了实验系统，通过实验和解析评估方法完成了单一式和复合式俘能器性能比对和评估；研究表明，所研究的混合型振动俘能器相对常规振动能量俘集原理可实现较宽的频率范围及多模态振动能量俘集，且能量俘集效率明显提高，具有较好的应用前景。

Abstract：In order to improve energy conversion efficiency and working frequency bandwidth of a single frequency piezoelectric vibration energy harvester, a new hybrid energy harvester system model was proposed combining piezoelectric and electromagnetic energy conversion mechanism. The system was composed of a PZT cantilever beam, an elastically suspended magnetic mass, a magnet block attached to the cantilever beam free-end and a resonator. The resonator was used to increase mode number of the system, and the magnet block was introduced to increase the system’s nonlinearity. Based on this hybrid vibration energy harvester system, an improved continuum electromechanical coupled analytical model was constructed and solved with Runge Kutta algorithm. Then, a prototype for the vibration energy harvester was developed, and a test system was built. The performance comparison and evaluation were completed with tests and the analytical evaluation method for the single frequency type energy harvester and the hybrid one. The study showed that compared to the conventional vibration energy capture principle, the proposed hybrid vibration energy harvester can be used to realize multi-mode vibration energy collection within a broader frequency range; its energy capturing efficiency is improved obviously, so it has better application prospects.
