Performance Analysis of a Magnetorheological Damper with Energy Harvesting Ability

Abstract

A magnetorheological (MR) damper with energy harvesting ability was proposed based on electromagnetic induction (EMI) principle. The energy harvesting part was composed of a permanent magnet array and inducing coils which move vertically. This device could act as a linear power generator when the external excitation was applied, and the kinetic energy could be converted into electrical energy due to the relative linear motion between the magnets array and the inducing coils. Finite element models of both the MR damper part and the linear power generator part were built up separately to address the magnetic flux distributions, the magnetic flux densities, and the power generating efficiency using ANSYS software. The experimental tests were carried out to evaluate the damping performance and power generating efficiency. The results show that the proposed MR damper can produce approximately 750 N damping forces at the current of 0.6 A, and the energy harvesting device can generate about 1.0 V DC voltage at 0.06 m·s−1excitation.

“…Using electromagnetic induction technique, an energy conserving device was suggested an electrical energy is developed, when external motion applied in between magnets and induced coils [31]. The self-power efficiency of the EMI, calculates the damping force, Figure 14 device produce approximately 750 N for 0.6 A current and 1 DC voltage [32].…”

Study of an Energy-Harvesting Damper Based on Magnetic Interaction

“…Attention has been paid to magnetic fluid-based devices that can act as passive or active fluids assisting in the generation of different grades of damping power, reducing friction and assisting in heat dissipation, in order to avoid an increase in temperature from non-recovered energy. Significant work has also been carried out on magnetorheological dampers [ 9 , 10 ], and even with energy-harvesting ability [ 11 ]. Some studies can also be found on ferrofluids and their application on damping [ 12 ], their application to energy harvesting [ 13 ], and for their use in automotive applications [ 14 ].…”
