“…Studies of power potential in regenerative vehicle suspension have reported a range of harvestable energy values between 46W and 7500 W using different techniques [8]- [10], [12]- [15]. In a different study, Kawamoto et al [17] reported a model in which 15.3W energy was recovered from one of the shock absorbers of a vehicle at 50 mph on the C class road with a vibration above 2 Hz.…”

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.

“…It is noted that the inductance and the inertia of the rotor would not dissipate energy. In common with most previous investigations [17], inductance and the inertia of the rotor are ignored in this study, and the simplest form of electromechanical coupling, V e = I(R in + R load ) is assumed in the circuit. Therefore, we can get the pressure drop of the motor from Equations (9) to (12) as:…”

“…Table 2 shows the values of the maximum energy-recyclable power at the natural excitation frequencies. Through numerical simulations and basic experiments, Suda and Shiiba [17] concluded that the harvest energy would drop as the load resistance decreased, while Okada and Harada [1] drew a conclusion that harvest energy would rise as the resistance decreased in high excitation frequency range. From Figs.…”

This paper presents a new kind of shock absorber, hydraulic electromagnetic energy-regenerative shock absorber (HESA), which can recover energy from vibration of vehicles. The road excitation frequency, load resistance and damping ratio are found to greatly affect the energy recovery of HESA. Based on a quarter-car model, the optimal load resistance and damping ratio for maximizing the energy-recyclable power are discussed. The results indicate that for any excitation frequency, the energy-recyclable power first increases then decreases with the load resistance increase, and the optimal load resistance is changeable as the excitation frequency changes. Moreover, the energy-recyclable power is more sensitive to excitation frequency than to damping ratio, and the ideal excitation frequency for energy recovery is around the wheel resonant frequency. The exploration of active control of HESA confirms that the damping force varies with the load current magnitude, and the active control can be realized by appropriate matching.

“…In fact, there are several types of energy regenerative suspension designs already under investigation, such as hydraulic storage suspension [1], battery coil induction suspension [2], rack and pinion suspension [3], ball screw suspension [4] and linear motion suspension [5]. In recent years, researchers worldwide have made attempts on the vehicle vibration control and energy regeneration, including theoretical and experimental progresses [6][7][8][9]. Developments achieved in power electronics, permanent magnet materials, and microelectronic systems enable the possibility of actual implementation of electromagnetic actuators in order to improve the performance of vehicle suspension systems [10].…”

To improve the vehicle performance such as ride comfort and road handling, the active suspension system should be used. However, the current active suspension system has a high energy consumption therefore reducing the fuel economy. In this paper the vibration excited by road unevenness is treated as a source of mechanical energy. It is being converted into electrical energy to compensate for the energy consumption by the active suspension. To achieve this task, an electromagnetic active suspension system has been introduced. The power generated from this device has been used as input power of the pump of the hydraulic actuators. Adaptive neuro-fuzzy controllers have been designed to generate a signal to control the valves of the hydraulic actuators.
