摘　　要：为了提高汽车燃油经济性,同时提高道路处理和平顺性,提出了一种将汽车悬架的振动运动转化为发电机单向旋转运动的再生式液压减振器系统。分析了系统的工作原理,建立了考虑水力流动、旋转运动和动力再生等因素影响的数学模型,在不同正弦输入激励、负载电阻和蓄能器容量对系统进行了试验研究。结果表明,在正弦波激励1 Hz频率和25 mm幅值下,当蓄能器容量设置为0.4 L,负载电阻为20Ω时,可恢复功率为280 W,效率约为40.75%;使用可变的负载电阻和蓄能器容量,可以满足重型运输车减振器所需的适当阻尼特性;该系统以最大限度地提高了再生、乘坐舒适性和操纵性能。In order to improve the fuel economy of automobile and to improve the peace and smoothness of road treatment, a kind of regenerative hydraulic shock absorber system which transforms the vibration motion of automobile suspension into one direction rotation of the generator is proposed. The working principle of the system was analyzed, and a mathematical model considering the influence of hydraulic flow, rotational motion and dynamic regeneration was established. The system was tested under different sinusoidal input excitation, load resistance and accumulator capacity. The results show that, under the sine wave excitation 1 Hz frequency and 25 mm amplitude, when the accumulator capacity is set to 0.4 L and the load resistance is 20 Ω, the recoverable power is 260 W and the efficiency is about 40%. With the variable load resistance and accumulator capacity, the appropriate damping characteristics needed for the shock absorber of heavy truck can be satisfied. The system provides reference for maximizing regeneration, riding comfort and handling performance.
