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.

This paper discussing all the design literature review for electromagnetic suspension systems for passenger vehicle. Electromagnetic suspension is the alternative for existing conventional suspension system that uses passive suspension system. Generally, linear motor is used in the design of the suspension. This is due to the behavior of the motor that can exert linear force directly to the attached load. In addition, the linear force from linear motor is controllable. This paperreview with the effects of all types of electromagnetic suspension systems to the passenger`s comfort. The reliability of fully active suspension system for vehicle also highlighted in this paper.A quarter-car model is used to assess the vehicle body vibration. This paper also deals with regenerative properties of linear motor that can improve the performance of lightweight vehicle.

“…The fact was verified by experimental results that the goal of energy harvesting of proposed regenerative suspension could be achieved under specific conditions that were derived from the energy balance analysis. Effect of equivalent damping ratio on the performances of isolation and regeneration was analyzed by Okada and Harada [7], showing that larger damping ratio led to both better vibration isolation and more regenerated energy of high-frequency vibration as well.…”
