摘要:
国内重载货运列车的迅速发展，对长大编组列车空气制动系统制动性能进行有效试验具有很大难度。基于每辆车制动相似性,以及整车空气波、制动波传递规律，建立了半实物列车制动系统仿真平台。在对采用典型空气制动机的小编组列车进行制动性能试验的基础上，建立了整列车的制动和缓解模型。采用气容充放气数学模型进行仿真计算，并结合修正函数进行实时修正，可实现半实物列车制动系统仿真平台的实时控制功效，为建立智能化试验平台打下较好的数学模型基础。
Abstracts:
With the rapid development of domestic heavy\|duty freight trains, there comes tremendous difficulty in effectively testing the braking performance of the air braking system of long formation trains. Based on the similarity of braking of each vehicle and the regular pattern of air wave and braking wave transmission through the whole vehicle, a semi\|physical train braking system simulation platform is established. Based on the braking performance test conducted on a small formation train that adopts typical air brake, the whole train braking and mitigation model is established. Simulation calculation is conducted using gas volume charge and discharge model, and real\|time correction is performed with correction function, which can realize real\|time control of the semi\|physical train braking system simulation platform, laying an ideal mathematical model foundation for establishing intelligent test platform.
