Abstract
本发明公开了一种利用桥梁悬索振动能量的压电‑电磁纳米发电机，该装置由内部直线轴承在悬索上进行反复摆动，直线轴承会带动激励磁铁一起运动，激励磁铁激励被激励磁铁进行运动，被激励磁铁带动两边的法兰直线轴承运动一起运动，法兰轴承沿着悬索运动，驱动连接片与压电片夹持架组成的折纸结构，通过运动激励压电片进行发电；激励磁铁在左右摆动的过程中穿过外壳上的铜线圈，利用电磁发电的原理发电。本发明涉及纳米发电机领域，特别涉及一种利用桥梁悬索振动能量的压电‑电磁纳米发电机。压电‑电磁纳米发电机的结构较为简单，通常不需要复杂的机械运动部件，因此可以减少机械故障和维护成本。只要设计合理，维护频率较低，能长期稳定工作。
