Abstract

Brazilian freight railways are characterized by operating high-capacity rail vehicles, the growth of production occurs parallel to the development of continuous monitoring technics, data acquisition, and learning tools. This direction may be unfeasible by the characteristics of ore freight trains in Brazil, where most of the wagons do not have any electrical energy source along with the composition to power sensors. To solve this problem, this paper investigates the viability of piezoelectric vibration energy harvesters, the orthogonal spiral structure associated with permanent magnets, working in Heavy Haul environment. This study uses the acceleration profile of a multibody dynamic simulation of a GDE wagon with two three-piece ride control bogies running through a track with FRA 5 irregularities. The OSs presented a promising future in the railway environment during this investigation, with its compact configuration for ultralow frequencies. And the magnet force introduction has increased the energy production of a OSs by 81.83%, reaching a value of 54.5 mJ.
