摘　　要：通过路轨两用消防车轨道行走的要求设计了轮边油马达独立驱动方案,建立了闭式液压驱动系统。结合消防车的最高车速、最大爬坡度和最大加速度等轨道行驶性能指标,对液压系统中双向定量马达和液压泵的选型进行了研究。在AMESIM中进行液压驱动系统的建模仿真,得到了车辆在不同的加速和上坡过程中,系统的压力响应和车辆的速度响应。所得结论验证了该液压系统满足车辆的动力性和液压系统的稳定性要求。Based on rail running requirements of the fire engine, four wheel motors are used in the inde- pendent diriving system, and closed hydraulic system is designed. Combined with the fire engine＇s perform- ance indexes, parameters of constant displacement motor and hydraulic pump are selected and matched. The dynamic simulating of system＇s pressure and engine＇s velocity in different accelerating and climbing condi- tions are processed under the AMESIM simulation environment. The conclusions prove that the hydraulic system satisfies the engine＇s power performance need and the hydraulic system＇s stability need.
