Electromagnetic harvesters need to be designed with a mechanism to amplify the coil relative velocity to ensure compact size and lower weight. This paper discusses a novel technique to use fluid link for velocity amplification in an electromagnetic shock absorber. Incorporation of the fluid amplification significantly improves harvested power, without affecting the system dynamics. Numerical modelling and experimentation of a prototype shock absorber comprising of high energy rare earth magnets have been presented. Peak coil voltage of 0.60–24.2 V was recorded during experimentation on the prototype. Experimental and simulation results validate that incorporation of the fluid amplification link improves the harvested electric power by 9702%. Comprehensive design procedure for better harvesting efficiency and vibration isolation has been discussed. Lastly incorporation of the shock absorber in McPherson strut suspension is illustrated. The real size version will be able to harvest peak power of 18–227 W for the suspension velocities of 0.15–0.4 m/s.

“…Successively, the studies on the regenerative SA have been concentrated on three different categories [19]: electromagnetic, hydraulic and mechanical designs. The first one is based on an electromagnetic method to generate the electric power, based on a linear electromagnetic regenerative SA that uses the electromagnetic induction to convert the kinetic energy of vertical oscillations into electricity [20]. The second category harvests the vibration energy and converts it into electricity, thanks to the oscillatory motion to drive a hydraulic motor, which is connected to a power generator [21].…”

The field of the Electric Vehicles (EVs) is becoming a strategic laboratory for new solutions focused on the energy saving and/or the renewable energy sources. Regenerative brakes are well known and already applied in recent cars. In this paper, instead, the attention is focused on a regenerative Shock Absorber (SA), which converts its vibration-induced by the road roughness-in electrical energy. The vibration is transmitted to an electric generator through a mechanical component. Finally, the produced energy can be stored in a super capacitor for a future use. The paper proposes a Simulink-based model of this regenerative SA and compares the energy performance when the vehicle travels roads with different roughness, scientifically defined by means an index, said IRI.

Abstract-Shock absorbers or dampers are used to maintain the contact between the vehicle's tires and road surface, to absorb the vibrations generated from the road disturbances and recently they are used in energy harvesting. In this study, a hybrid regenerative shock absorber system containing hydraulic and electromagnetic (EM) damper mechanisms was designed to generate electricity. The energy harvesting was applied from the hybrid regenerative shock absorber using excited linear movement. A total of 0.25W for 0.004 m/s, 0.4W for 0.0045 m/s and 0.66W for 0.005 m/s was harvested using 80Ω and 2Ω external resistors for hydraulic part and for EM part, respectively, at 15 mm amplitude in response to the specified excitation. The mean power for 0.005 m/s was calculated as 0.003W for coil and as 0.56W for generator. The harvested energy was measured as low for measured velocities, however, the amount of harvestable energy rate or efficiency has increased with increasing velocity.Index Terms-Electromagnetic damper, energy harvesting, shock absorber, hydraulic damper, regenerative damper.
