摘　　要：提出并设计了一种并联式液压混合动力模拟车辆,在需要频繁刹车和起步的路况,可将制动的能量回收并储存为液压能,然后可在起步等工况下释放,进而降低车辆在启停过程中的油耗和废气排放,延长刹车设备的使用寿命。通过仿真软件AMESim对车辆的液压系统进行建模仿真,分析其动态特性,研究蓄能器容积和液压泵排量等关键参数对车辆动态特性的影响,结果表明选用大容积的蓄能器和大排量的液压二次元件有助于提高液压混合动力模拟车辆的性能。In this paper, a parallel hydraulic hybrid simulation vehicle is proposed and designed. Under the road conditions requiring frequent braking and starting, the braking energy can be recovered and stored as hydraulic energy, which can be released under starting or other working conditions. The designed vehicle can reduce the fuel consumption, reduce exhaust emission and increase the service life of braking equipment. The hydraulic system of the vehicle is modeled and simulated by the simulation software AMESim. The dynamic characteristics are analyzed and the effects of accumulator volume and hydraulic pump displacement on the dynamic characteristics of the vehicle are also studied. The results show that the selection of large volume accumulator and large displacement hydraulic secondary components is helpful to improve the performance of the designed vehicle.
