智能化制动试验平台的制动控制研究
Research on Braking Control of Intelligent Braking Test Platform

一直以来，对于长大货运列车的制动性能及引起的纵向动力学效果的数据难以在真实运行的列车上进行分析和采集，往往会耗费过多的人力、物力，还不能够得到精确的数据。通过在实验室内的单车制动试验平台模拟实际编组运行的货运列车，从而获得的制动数据可以为研究真实的列车制动效果提供有效的依据。本文采用LabVIEW软件，通过TCP通讯实现了LabVIEW和非NI公司出品的控制板卡间的数据通讯，完成了对制动试验平台的制动功能的控制，与采用数值仿真方法进行的空气制动曲线进行了对比，并采用AMESim对中继阀的特性进行了研究。仿真与实验结果证明，该方法可以实现制动试验平台单车制动系统良好的控制，控制效果和数值仿真结果相符。
For a long time, it is difficult to analyze and collect the data of the braking performance and the longitudinal dynamic effect caused by the long and large freight trains on the real running trains, which will often consume too much manpower and material resources but can not get accurate data. The braking data obtained from the simulation of freight trains in actual marshalling on the single-car braking test platform in the laboratory can provide an effective basis for the study of the actual braking effect of trains. In this paper, the data communication between LabVIEW and the control board produced by non-NI Company is realized by using TCP communication with LabVIEW software, and the control of the braking function of the braking test platform is completed, compared with the air brake curve by numerical simulation method, and studied the characteristics of relay valve with AMESim. The results of the simulation and experiment show that this method can achieve good control of the single-car braking test system, and the control effect is similar to that of numerical simulation.
