摘要振动能量采集能够将外部环境中的振动能转化为电能，具有绿色可持续、节能环保、设计灵活等优势，在工业、生物、医学、军事等领域具有广阔的应用前景。为使振动型能量采集器适应更为复杂多变的工作环境，提高其采集功率和工作频带，提出一种多梁结构—Z型梁结构压电式能量采集器。理论分析了该采集器的固有振动特性，并通过有限元分析了结构尺寸、激励大小与方向、外部负载等参数对能量采集器性能的影响规律。结果表明，通过合理的动力学设计，Z型梁结构压电式能量采集器可以实现多模态共振频率下的有效能量采集。

Abstract：Vibration energy harvester transforms the vibration energy from the external environment into electrical energy, which has the advantages of green and sustainable, energy saving and environmental protection, flexible design. It has a broad application prospect in fields of industry, biology, medicine, military. In order to make the vibration energy harvester adapt to more complex and changeable working environment, and improve its harvesting power and working frequency band, a kind of multi beam structure, namely Z-shaped beam structure piezoelectric energy harvester, is proposed in this study. Natural characteristics of the designed energy harvester are investigated theoretically. Moreover, effects of structure size, excitation direction, external load and other parameters on the performance of energy harvester is discussed by the finite element method. Results show that the Z-shaped beam piezoelectric energy harvester would achieve multi-mode energy harvesting through a reasonable analysis and design.
