In this paper the authors investigate the energy harvesting in railway bridges and analyse the performance
under different operational conditions. An approximation based on modal superposition is proposed for the
computation of the energy harvested from train-induced bridge vibration. This approach is consistent with
the analytical modal solutions of the simply-supported Bernouilli-Euler beam transverse response under
moving loads. The influence of the bridge maximum dynamic response and cancellation phenomena, the
tuning effect of the harvester device and the relevance of different modal contributions on the harvested
energy are studied using a single-degree of freedom system as a simplistic mechanical approach. Later, a
piezoelectrically coupled lumped parameter model is used to investigate the available energy due to High-
Speed train passages at different circulating speeds. Finally, the feasibility of energy harvesting is evaluated
from the experimental data measured by the authors in a railway bridge from the Madrid-Sevilla High-Speed
line. The obtained results allow quantifying the harvested energy in a time window of three and a half hours
and twenty train passages. [-]
