    • openAccess   3D printed energy harvesters for railway bridges-Design optimisation 

      Cámara Molina, Javier Cristóbal; Moliner, Emma; Martínez-Rodrigo, María D.; Connolly, D. P.; Yurchenko, D.; Galvín, Pedro; Romero, A. Elsevier (2023)
      This paper investigates the optimal design of 3D printed energy harvesters for railway bridges. The type of harvester studied is a cantilever bimorph beam with a mass at the tip and a load resistance. These parameters ...

    • openAccess   Ballasted track interaction effects in railway bridges with simply-supported spans composed by adjacent twin single-track decks 

      Sánchez Quesada, Juan Carlos; Moliner, Emma; Romero, A.; Galvín, Pedro; Martínez-Rodrigo, María D. Elsevier (2021-09-08)
      This paper is devoted to track-bridge interaction phenomena in railway bridges of short simply-supported (SS) spans composed by ballasted tracks. These structures may experience high vertical acceleration levels under ...

    • openAccess   Design, tuning and in-field validation of energy harvesters for railway bridges 

      Cámara Molina, Javier Cristóbal; Romero, A.; Moliner, Emma; Connolly, D. P.; Martínez-Rodrigo, María D.; Yurchenko, D.; Galvín, Pedro Elsevier (2024)
      Energy harvesters are a promising technology for powering infrastructure condition monitoring systems without batteries. When deployed on railway bridges they are typically tuned to the bridge’s natural frequency, however ...

    • openAccess   Energy harvesting analysis in railway bridges: an approach based on modal decomposition 

      Romero, A.; Cámara Molina, Javier Cristóbal; Moliner, Emma; Galvín, Pedro; Martínez-Rodrigo, María D. Elsevier (2021)
      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 ...
