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。
Rail transit vehicles need frequent braking during operation, which istes excessive energy. In order to recover and reuse this part of braking energy, a pneumatic recovery system of braking energy for rail vehicle is proposed. Its mathematical model is deduced. The simulation model is established by AMESim simulation software, and its dynamic characteristics are analyzed. The effects of parameters such as piston diameter, cylinder stroke, check valve opening pressure and clearance volume on the recovery performance were studied. On this basis, the optimal design of the recovery system based on the orthogonal table is obtained, and the optimal combination of the parameters is obtained, which provides a theoretical basis for the practical engineering application.
