Research on Power Generation Performance of Speed Bump Vibration Energy Harvester under Random Excitation

  • 摘要: 本文将双稳态振动能量发电装置引入到减速带结构中,提出了一种双稳态减速带振动能量捕获装置,建立了其力学模型和控制方程。假定车重和车速符合正态分布,利用数值仿真方法,分别针对车重和车速其中一个参数随机变化及车重和车速两个参数同时随机变化这两种情况,研究并分析了车重和车速均值和方差对减速带发电功率的影响规律,研究结果表明,减速带发电系统输出功率随着车重均值和方差的增加而增大。不同车重均值的车辆通过减速带时,减速带发电功率最大值所对应的车速均值不同,最佳车速均值约在20 ~ 25 km/h之间,减速带发电功率随着速度方差的增大而逐渐减小,在较大发电功率下,双稳态发电振子在两个平衡点间产生大幅混沌运动,处于有利于发电的状态.
