基于循环变量法的重载列车纵向力仿真分析

Longitudinal Force Simulation for Heavy Haul Train Based on Cycle Variable Method

重载列车运行实现的基础是动力学建模和牵引仿真计算。针对传统列车仿真模型的不足采用了基于循环变量的重载列车纵向力仿真模型,并对2Loco+14Car、9单元编组重载列车进行了建模仿真,验证了模型的正确性。同时给出了该编组在多种工况下的车钩力时程曲线及其沿整列车分布的规律,证明该编组列车符合列车安全运行要求。

The operation of heavy haul train was based on dynamics modeling and traction simulation calculation. According to the limitation of traditional research, a mathematical simulation model of longitudinal force of heavy haul train based on cycle variable was established. The model had been verified by the simulation though a train marshalling of 2Loco＋14Car, 9 units. The results of the coupler force curves and its distribution along the whole train in different running conditions were provided, which verified that a train marshalling of 2Loco＋14Car, 9 units could meet the safe operation requirement.
