摘要

利用双稳态压电悬臂梁俘能装置将雨滴动能转换为电能。建立双稳态压电悬臂梁俘能装置的力学模型及控制方程，通过简化获得了单个雨滴冲击力的数学模型，采用对数正态分布函数模拟了不同降雨强度下雨滴直径的随机分布。利用数值仿真，研究了不同雨滴直径及不同降雨强度对俘能系统动力学特性及发电性能的影响。搭建了雨滴冲击发电实验装置，实测雨滴降落高度对系统输出电压的影响。研究结果可为利用雨滴冲击发电探索新型能源的研究提供部分参考。

Abstract

Bistable piezoelectric cantilever beam energy harvester can be used to convert raindrop kinetic energy into electrical energy.Here, the mechanical model and control equation of bistable piezoelectric cantilever beam energy harvester were established.The mathematical model of single raindrop impact force was obtained through simplification.The lognormal distribution function was used to simulate the random distribution of raindrop diameter under different rainfall intensities.Effects of raindrop diameter and rainfall intensity on dynamic characteristics and power generation performance of the energy harvester system were studied using numerical simulation.The test device for raindrop impact to generate electric energy was built, and effects of raindrop falling height on the system output voltage were actually measured.The study results could provide a reference for study on exploring new energy sources by adopting raindrop impact to generate electric energy.
