Abstract:

This study proposes various methods to harvest the mechanical energy present in railcar suspensions and railroad tracks to generate low-power electricity that is suitable for onboard or trackside electronics, using electromagnetic generators. A compact electromagnetic energy harvester that can be installed onboard railcars or wayside on railroad tracks is designed, fabricated, and tested. The design integrates a mechanical motion rectifier (MMR) with an embedded one-way clutch in the bevel gears, to convert the bi-directional mechanical energy that commonly exist in the form of vibrations into a unidirectional rotation of the generator. The ball-screw mechanism is configured such that it has reduced backlash and thus can more efficiently harvest energy from low-amplitude vibrations.
