“…7a. Road tests have shown that the electromagnetic energy regenerative suspension has improved off-road performance, but there is still room for improvement in regenerative [27]. After verifying the feasibility of the rack-pinion energy regenerative suspension, researchers conducted in-depth research on the coordination between its reliability, energy regenerative performance, and functions.…”

The active suspension has undoubtedly improved the performance of the vehicle, however, the trend of "lowcarbonization, intelligence, and informationization" in the automotive industry has put forward higher and more urgent requirements for the suspension system. The automotive industry and researchers favor active energy regeneration suspension technology with safety, comfort, and high energy regenerative efficiency. In this paper, we review the research progress of the structure form, optimization method, and control strategy of electromagnetic energy regenerative suspension. Specifically, comparing the pros and cons of the existing technology in solving the contradiction between dynamic performance and energy regeneration. In addition, the development trend of electromagnetic energy regenerative suspension in the field of structure form, optimization method, and control technology prospects.

“…Mechanical regenerative suspension normally uses hydraulic/pneumatic power to convert the kinetic energy into potentially recoverable mechanical energy with control methods, which can be stored for later use [12][13][14][15][16][17]. Electromagnetic regenerative suspension converts the relative vibration isolation into the linear or rotary motion using electric generators to produce recoverable electricity [18][19][20][21][22][23][24][25][26][27][28]. Hydraulic regenerative suspension converts the reciprocating linear motion into unidirectional rotary motion through the designed hydraulic circuit, and hence to produce electricity by a generator [29][30][31][32][33].…”

In order to improve the rail vehicle fuel economy, this paper presents the feasibility of power regenerating dampers (PRDs) in railway vehicle primary suspension systems, and the evaluation of the potential and recoverable power that can be obtained. The power regenerating damper is configured as a hydraulic-electromagnetic based railway primary vertical damper and is evaluated in both the 'Parallel Mode' and 'Series Mode' (with and without a viscous damper). Hydraulic configuration converts the linear behavior of the track into a unidirectional rotating of the generator, while the electromagnetic configuration provides a controllable damping force to the primary suspension system. Several case studies of generic railway vehicle primary suspension systems configured to include a power regenerating damper in the two different configuration modes are modelled using computer simulation. The simulations are carried out on measured tracks with typical irregularities for a generic UK passenger route. The performance of the modified vehicle is evaluated with respect to key performance indicator, including regenerated power, ride comfort and running safety. The results are concluded that PRDs are capable of replacing conventional primary vertical damper, regenerating the power and providing the desirable dynamic performances simultaneously. A peak power efficiency of 79.87% is obtained from 'Series Mode' on a top quality German ICE track ('Track270') at a vehicle speed of 160mph theoretically.

Electromagnetic actuated active suspension (EAAS) benefits energy harvesting while providing active control. However, the inertia of the actuator introduces an equivalent mass coupled with the sprung and unsprung mass. In addition, the specific structure of the suspension features structure non-linearity, which results in the perturbation of the equivalent mass of the actuator, the variation of the transmission ratio of the actuator output torque to the actuator force at the wheel side and an extra force to be compensated with. A dynamic model of active control considering the equivalent mass and the structure non-linearity is proposed. Based on a gearbox type EAAS, respective non-linearity is studied. For multi-objective optimization, a robust controller is designed with proper weighting functions. A virtual prototype of the EAAS is built and simulated with a bump/pothole and random excitation road profiles. Results show that neglecting the structure non-linearity effects influences the accuracy of active control. The investigation of this paper provides a fundamental methodology for the control design of actual applications of EAASs.
