摘要：
In this paper, the authors investigate the energy harvesting in railway bridges. An analytical model is proposed for the estimation of the energy harvested from train-induced bridge vibration. The typology of the energy harvester studied in this work is a bimorph beam consisting of two piezoelectric patches on a substructure with a seismic mass. The energy harvested is tuned to find the optimum operating point for maximum power production. The optimization problem is constrained by the integrity of the substructure, and it is solved using a genetic algorithm. Finally, the feasibility of the proposed model is verified against an existing analytical solution and finite element model.
