空重车混合编组方式对重载列车纵向力的影响

建立了1万吨级重载列车纵向动力学仿真模型，使用Runge-Kutta法对其运动微分方程进行了求解，并编制了Fortran软件求解程序。以紧急制动工况为例，比较了不同空重车编组方式与纯重车的车钩最大压缩力．对不同牵引方式下的空重车混编提出了合理建议．有助于提高列车运行安全性能。

Influence of Mixed Marshalling of Light and Heavy Vehicles on Heavy Haul Trains＇ Longitudinal Force

This paper sets up a longitudinal dynamic simulation model of ten-thousand-class heavy haul trains and solves the differential equation of motion with the method of Runge-Kutta, as well as works out the solving programs by Fortran software. Taking the emergency braking case for instance, it compares the maximum compress coupler force of different mixed marshalling of light-heavy vehicles and pure heavy vehicles, followed by the reasonable suggestions of light-heavy mixed marshalling under different traction types, which is helpful to trains safety performance improvement.
