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 ... -
Analysis of the influence of the ballast track in the dynamic behaviour of single-track railway bridges of different typologies
Chordà Monsonís, Josep; Martínez-Rodrigo, María D.; Galvín, Pedro; Romero, A.; Moliner, Emma Universitat Politècnica de València (2021)Short-to-medium span simply-supported (SS) railway bridges are prone to experience high levels of vertical acceleration due to train passage. The necessity of predicting accurately their dynamic behaviour for design, ... -
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 ... -
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 ... -
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 ... -
Influence of track modelling in modal parameters of railway bridges composed by single-track adjacent decks
Sánchez Quesada, Juan Carlos; Moliner, E.; Romero, A.; Galvín, Pedro; Martínez-Rodrigo, María D. Universitat Politècnica de València (2022-05-01)A significant number of railway bridges composed by simply-supported (SS) spans are present in existing railway lines. Special attention must be paid to short to medium span length structures, as they are prone to ... -
Optimal design and application of 3D printed energy harvesting devices for railway bridges
Cámara Molina, José Carlos; Romero, A.; Galvín, Pedro; Moliner, Emma; Martínez-Rodrigo, María D. CRC Press (2023-06-28)In this paper, the authors investigate energy harvesting on railway bridges. The tuning frequency for the optimal design of cantilever based 3D printed energy harvesters is studied. An analytical model to represent the ...
