Energy Harvesting in High-Speed Railway Bridges Using Magnetoelastic Materials

This paper explores energy harvesting from vibrations induced by train passages in High-Speed railway bridges using magnetoelastic material (MsM).This research proposes an analytical approach derived from a variational formulation to obtain the governing equations of MsM.Moreover, an optimal design procedure is considered to produce the maximum power.Finally, the proposed model is verified in a case study using experimental records of a railway bridge under operating conditions.The conclusions drawn from the experimental case study show that the harvested energy in the train passage could be E=5.28 mJ.The results of this analysis could be helpful for low power consumption devices, nodes, and sensors of monitoring systems in remote areas, and also for the development of harvesters as direct structural health monitoring devices.
