Abstract In this work, an axial-type vibration energy harvester with an impact-sliding structure that uses a magnetostrictive Permendur (Fe-Co-V) rod was produced and its power generation properties were measured. It was found that all the peak frequencies analyzed using the FFT method from the experimentally obtained voltage waveforms were consistent with the calculated inherent frequencies of the axial vibration of the rod. Therefore, the power generation by the proposed harvester likely resulted from the inherent axial vibration of the magnetostrictive rod. Furthermore, the maximum output energy obtained in this work was 1592 µJ, which was generated by a harvester with 3000 coil turns and two magnets under a load resistance of 3 kΩ. It was found that the maximum output energy was generated when the load resistance was close to the coil impedance at the inherent frequency of the axial vibration of the rod.

使用磁致伸缩铁钴钒合金棒生产具有冲击滑动结构的振动能量收集器

摘要 在这项工作中，生产了一种使用磁致伸缩 Permendur (Fe-Co-V) 杆的具有冲击滑动结构的轴向式振动能量收集器，并测量了其发电性能。发现使用FFT方法从实验获得的电压波形分析的所有峰值频​​率与计算的杆轴向振动的固有频率一致。因此，所提出的收割机的发电可能是由磁致伸缩杆的固有轴向振动引起的。此外，在这项工作中获得的最大输出能量为 1592 µJ，这是由具有 3000 匝线圈和两个磁铁、负载电阻为 3 kΩ 的采集器产生的。
