“…The vehicle suspension system is the fundamental device for improving ride comfort and handling stability. [1][2][3][4] Recently, researchers found that the energy of the suspension vibration can be regenerated by means of magnetic suspension [5][6][7][8][9][10][11] and piezoelectric suspension. [12][13][14][15][16] In Segal and Lu, 17 the influence of suspension damping, tires, and road surface roughness on the vehicle running resistance was analyzed, and it was noted that, when the vehicle drove at a speed of 48 km/h, the damper dissipated approximately 200 W of energy.…”

This article concerns a hybrid vehicle suspension system that can regenerate energy from vibrations. To further improve the performance of the hybrid vehicle suspension system, the design of the energy-regenerative circuit is investigated. First, the force tests of the linear motor used in the hybrid vehicle suspension were carried out, and the key parameters of the linear motor were obtained. Then, the selection procedures of the protective resistance, inductance, and initial terminal voltage of the super capacitor were discussed. These aforementioned parameters' values were determined by considering the impact of the hybrid suspension on the dynamic performance indexes and the energy-regenerative efficiency. Simulations showed that, in comparison to the original hybrid suspension system, the designed hybrid suspension effectively improved the energy-regenerative efficiency, and that the dynamic performance indexes of the suspension were synchronously improved. Given the result of the simulation analysis, which were validated by bench tests, it is shown that the optimized energy-regenerative circuit presents an enhanced regeneration efficiency, with an improvement of nearly 13% compared to the original suspension system.

“…Various successful works suggest that the active suspension can effectively improve the vehicle dynamics and resolve the contradictions between vehicle ride comfort and stability. For example, according to Gysen et al (2011), compared to the passive suspension, the active suspension could improve the ride comfort by 36%, or achieve a reduction of 54% in the dynamic tire load, which is beneficial to road holding performance and vehicle stability.…”

Active suspension can effectively resolve the contradictions between vehicle ride comfort and stability. However, a new contradiction between the active suspension performance and efficiency is aroused. Active suspension with excellent performance requires high actuation power and force in an aggressive condition, which is usually an excess capacity for normal conditions. To improve the efficiency and capacity utilization rate, this paper conducted an investigation on the efficiency and utilization rate of vehicle active suspension based on a seven degrees-of-freedom full vehicle mode with a linear quadratic Gaussian active suspension controller. The multiple objectives of active suspension performance and efficiency are integrally optimized via genetic algorithm with an elaborately designed penalty function. The proposed integration of multiple objectives is proved effective according to the comprehensive comparison analysis. The overall performance of the optimized suspension achieved the Pareto optimality. Not only a better balance between the ride comfort and stability is accomplished, but also the active suspension utilization rate is improved. By this method, the obtained Pareto optimality set can greatly improve the parameters matching and design of the active suspension.

“…The device which transformed vibration energy into hydraulic energy has been proposed by Chen et al, and the results from simulations and experiments indicated that it could lead to an improvement of ride comfort and a reduction of fuel costs as well [13,14]. Gysen prototype system produced for on-board experiments [15][16][17]. In addition, a hydraulic electromagnetic shock absorber (HESA) has been studied by Fang et al, in which oils in the absorber cylinder were derived from a hydraulic rectifier bridge, flowed towards one direction and finally drove the hydraulic motor generator.…”

To recycle the vibration energy of vehicles over rough roads, a hydraulic-electricity energy regenerative suspension (HEERS) was designed in the present work, and simulations were performed with focus on its performance. On the basis of the system principle, the mathematical model of hydraulic-electrical energy regenerative absorber (HEERA) and two degrees of freedom (DOF) suspension dynamic model were constructed. Using the model of HEERA, simulations on force-displacement and forcevelocity characteristics were performed with a 1.67 Hz frequency and a sinusoidal input adopted. And then in combination with HEERA model and two DOF suspension models, simulations on the performance of HEERS also were carried out. Finally, the influences of charging pressure and volume of the accumulator, hydraulic motor displacement, orifice area of check valve, and inner diameter of hydraulic pipelines on the performance of HEERA and HEERS were investigated in depth. The simulation results indicated that (i) the damping characteristic of HEERA was coincident with the damping characteristics of traditional absorber; (ii) the most remarkable influencing factor on the performance of HEERS was the hydraulic motor displacement, followed by orifice area of check valve, inner diameter of pipelines, and charging pressure of accumulator, while the effects of charging volume of accumulator were quite limited.
