The vehicle suspension system is the fundamental device for improving ride comfort and handling stability.^1–4 Recently, researchers found that the energy of the suspension vibration can be regenerated by means of magnetic suspension^5–11 and piezoelectric suspension.^12–16 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. Hsu¹⁸ deeply studied the active suspension based on the Linear-Quadratic-Gaussian (LQG) control strategy, and it was found that, when the vehicle was driving at a high speed of 96 km/h, the vibration energy can be regenerated by 400 J. Yu et al.¹⁹ analyzed the feasibility of the active energy-regenerative suspension, and the simulation results showed that, when the vehicle drove at 20 m/s on a C level road for 20 s, the energy dissipated by the passive suspension was 651 kJ. However, the feed-in energy cannot reflect the energy recovery capacity of the energy-regenerative suspension and the energy-regenerative efficiency should be used to reflect the energy-regenerative capacity. In Zhang et al.,²⁰ a novel regenerative shock absorber was designed and fabricated, and the double speed regenerative shock absorber utilizing the rack and pinion mechanism was applied to increase the magnet speed. The results showed that the proposed design can increase the output power by four times compared to the baseline design under the sinusoidal and random road input.

混合动力汽车悬架能量再生电路设计与实验研究

汽车悬架系统是提高乘坐舒适性和操纵稳定性的基础装置。^1-4最近，研究人员发现悬浮振动的能量可以通过磁悬浮^5-11和压电悬浮来再生。^12-16 Segal 和 Lu, ¹⁷分析了悬架阻尼、轮胎和路面粗糙度对车辆行驶阻力的影响，并指出，当车辆以 48 km/h 的速度行驶时，阻尼器消耗了大约 200 W 的能量。徐¹⁸深入研究了基于线性二次高斯（LQG）控制策略的主动悬架，发现当车辆以96公里/小时的高速行驶时，振动能量可再生400 J.于等人。¹⁹分析了主动能量再生悬架的可行性，仿真结果表明，当车辆在C级道路上以20 m/s的速度行驶20 s时，被动悬架耗散的能量为651 kJ。但馈入能量并不能反映能量再生悬架的能量回收能力，应采用能量再生效率来反映能量再生能力。张等人²⁰设计并制造了一种新型再生减震器，并应用利用齿轮齿条机构的双速再生减震器来提高磁体速度。结果表明，在正弦和随机道路输入下，与基线设计相比，所提出的设计可以将输出功率提高四倍。
