Diseño y simulación de un acumulador de energía vibracional electromagnética para aplicaciones en válvulas de control : diseño y simulación de un recolector de energía electromagnética en válvulas de control con carga no armónica.

Abstract

In this work, the electrical power that an electromagnetic generator can produce when assembled in a control valve was analytically investigated. The assembly in the control valve was carried out with the help of the Inventor software, an equivalent model was made through a damper spring mass system with a single degree of freedom, in order to obtain a mathematical model of the system, to be able to implement it in a simulation in the Matlab software. To carry out the simulation, some parameters are necessary, both the materials for the electromagnetic generator and the operation of the control valve; these parameters were obtained through research and applied to the simulation. The results are shown depending on the length of the cantilever beam between 1 mm and 5 mm because in that range is the geometry of maximum energy collection, a maximum power of 0.359mW could be obtained when working on a valve. control unit with a nominal diameter of 200 mm, a frequency of 3800 Hz and an amplitude of 0.0005 g. To achieve the maximum result, the input frequency and amplitude, the geometry of the cantilever beam and the caliber of the enameled wire are varied. . The results are then validated by comparing them with similar studies by other authors when implementing electromagnetic generators in systems with conditions close to those of this study.
