摘要

摘要: 环境中振动能量收集效率低的问题是当前压电发电技术研究的焦点。为了提高环境中振动能量的收集效率，研究了一种可以收集环境中多个方向振动能量的压电发电关键技术。首先，利用压电发电技术的基础理论建立压电悬臂梁的数学模型，并对其进行振动力学分析；然后利用ANSYS对压电悬臂梁进行有限元仿真分析，优化结构使其固有频率与环境振动频率相符；最后制作多向压电发电装置，对其进行理论分析和实验测试。实验结果证明，多向振动压电发电关键技术可以有效地提高环境中振动能量的收集效率。

Abstract: The problem of low efficiency of vibration energy collection in the environment is the focus of the research on piezoelectric power generation technology. In order to improve the collection efficiency of the vibration energy in the environment, the piezoelectric power generation technology for multi-direction collecting environment vibration energy is studied. First, the mathematical model of the piezoelectric cantilever is built by the basic theory of the piezoelectric power generation technology, and the vibration mechanics analysis is carried out. Then, the piezoelectric cantilever is analyzed using ANSYS finite element simulation, and the structure is optimized so that the natural frequency of the vibration frequency is consistent with the environment. And finally, the multi-direction piezoelectric device is developed, and its theoretical analysis and experimental testing are finished. The experimental results show that the multi-direction vibration of piezoelectric power generation key technologies can effectively improve the collection efficiency of vibration energy.
