On the target frequency for harvesting energy from track vibrations due to passing trains
(2019-01-01)
There is an increasing desire to monitor the structural integrity of railway tracks and the supporting ballast and subgrade. Track vibration has been proposed as a potential energy source to power wireless sensors for this ...
On the spectrum of rail vibration generated by a passing train
(2017-01-01)
Recent work in rail vibration has investigated methods for estimating track support stiffness from trackside vibration. This vibration, induced by the passage of a train, is mainly due to the load applied by the wheels, ...
An investigation into harvesting energy from sleeper vibration due to a passing train
(Universidade Estadual Paulista (Unesp), 2019-12-05)
The advances in microelectromechanical systems to power supply devices for monitoring the structural integrity, mainly for applications in remote areas or with difficult access, have made energy harvesting from ambient ...
Energy harvesting from the vibrations of a passing train: Effect of speed variability
(2016-10-03)
This paper builds on a previous study which investigated the amount of energy that could be harvested from the vibration induced by a passing train using a trackside energy harvester. In that study, the optimum parameters ...
