摘要

针对低频激励下多层PVDF堆叠压电悬臂梁发电性能展开研究，以提高悬臂式压电俘能器输出性能。建立多层PVDF堆叠压电悬臂梁集中参数模型，分析不同层数堆叠对谐振频率的影响关系，运用COMSOL Multiphysics对多层PVDF堆叠压电悬臂梁进行仿真，讨论不同层数、不同布置方式、负载等参数对系统输出功率的影响规律，并进行实验验证。结果表明：多层PVDF并联堆叠能够有效提高压电俘能器输出功率，单侧堆叠3层PVDF时输出功率可达单层压电悬臂梁的2.9倍，双侧各1层时输出功率是单层压电悬臂梁的2.2倍，研究结果为压电俘能器优化设计及工程应用提供了理论依据。

Abstract

The power generation performance of multi-layer PVDF stacked piezoelectric cantilever under low frequency excitation is studied in order to improve the output performance of piezoelectric cantilever. The lumped parameter model of multi-layer PVDF stacked piezoelectric cantilever is established, and the influence of different layers on resonant frequency is analyzed. The multi-layer PVDF stacked piezoelectric cantilever is simulated by COMSOL Multiphysics. The influence of different layers, different arrangement and load on the output power of the system is discussed and verified by experiments. The results show that the parallel stacking of multi-layer PVDF can effectively improve the output power of piezoelectric cantilever beam. The output power of unilateral stacking 3-layer PVDF is 2.9 times that of unilateral 1-layer piezoelectric cantilever. When one layer is arranged on each side, the output power is 2.2 times that of the unilateral one-layer piezoelectric cantilever. The research results provide a theoretical basis for the optimal design and engineering application of piezoelectric energy trappers.
