轨道交通车辆在运行过程中需要频繁制动,浪费过多的能量。为了回收再利用这部分制动能量,提出了一种轨道车辆制动能量气动回收系统,推导了其数学模型,利用AMESim仿真软件建立其仿真模型,并进行仿真研究,分析其动态特性。仿真研究了活塞直径、气缸行程、单向阀开启压力、余隙容积等参数对回收性能的影响。在此基础上,对回收系统进行了基于正交表的参数优化设计,得到了其最佳参数组合,为实际工程应用提供理论依据。

During operation railway vehicle requires frequent braking, which wastes too much energy. In order to recycle this part of braking energy, a pneumatic recovery system for railway vehicle braking energy was proposed and its mathematics model was deduced. By using of AMESim simulation software, the simulation model of the pneumatic recovery system was built and its simulation research was conducted to analyze its dynamic characteristics. Moreover, the effect of piston diameter, cylinder stroke, the opening pressure of check valve, clearance volume to the recovery performance of this system was researched by simulation. On this basis, the parameter optimization design of the recovery system was done based on orthogonal table and its best parameters combination was obtained. This will provide theoretical basis for practical engineering applications.
