一种新型宽频振动能量采集器的设计、优化与实验
Design,Optimization and Experiment of A New Broadband Vibration Energy Harvester
摘要
Abstract
Traditional cantilever piezoelectric energy harvesters are limited by their linear design and single-resonance frequency response,resulting in low energy harvesting efficiency under complex and variable environmental conditions.To address this limitation,this paper proposes a novel F-shaped piezoelectric energy harvester featuring three resonant peaks.The harvester system was designed and structurally optimized using COMSOL simulation software.Experimental tests were conducted to validate the simulation results.In order to further broaden the bandwidth of F-type harvester,mechanical stoppers were introduced at different positions on the two auxiliary beams.The influence of stoppers on the bandwidth and output voltage was analyzed experimentally.The results show that the operating bandwidth is greatly expanded from 4.73 Hz to 7.38 Hz by the introduction of the stoppers,which enhances the adaptability of the collector in complex environments.关键词
