Practical Performance of Magnetostrictive Vibration Energy Harvester in Highway Bridge
This study proposed and tested a novel energy harvester using magnetostrictive material (Fe-Ga alloy) on a highway bridge to investigate its practical performance. The device comprises a Fe-Ga element of 4 × 0.5 × 16 mm installed on a steel frame with a permanent magnet and wound about by a coil. First, a part of the elevated line of the highway bridge located in the Hokuriku district was tested to investigate the dynamic responses of the bridge caused by ordinary vehicle loads. Then, the weight attached to the tip of the frame was adjusted to allow the frame to vibrate with the frequency of the vibration source. As the results, with an attached weight of 312.8 g, the frequency of the frame’s oscillation matched the frequency of the vibration of the lateral brace between G1 and G2 main girders, which was estimated to be ~19 Hz. Moreover, a voltage of ~8 V at a vibration of ~19 Hz and 8.9 m/s2 was recorded by free damped vibrations due to ordinary vehicle loads.
