摘要

针对2万t组合列车存在的主控机车和从控机车通信信号延迟问题，基于多体动力学理论，建立了考虑通信延迟的列车纵向动力学仿真分析模型，仿真分析了列车在12‰长大下坡道循环制动过程中通信延迟对纵向冲动的影响规律和不同机车电制动力下通信延迟对纵向冲动的影响。结果表明：列车纵向拉钩力和压钩力均随着通信延迟的增大而增大，而且最大压钩力位置随通信延迟增大向车尾方向移动；通信延迟对负向加速度影响较为明显，即对于中部机车，其负向加速度随通信延迟的增大而增大；对于前部和后部货车，随通信延时增大其局部位置车辆负向加速度波动较大；在列车制动过程中通信延迟对纵向冲动的作用受机车电制动力影响较小，而在缓解过程中，机车电制动力越小，通信延迟对列车纵向冲动作用越显著。

Abstract

Focus on the communication delay between the master and slave control locomotive, a detailed longitudinal dynamic simulation model considering the communication delay was established based on the multi-body dynamics theory. The influence of communication delay on longitudinal impulse of train during cycle braking on 12‰ heavy and long descending grade was simulated. Furthermore, the analysis of influence of communication delay on longitudinal impulse under different dynamic braking forces were completed. The simulation results indicated that both the longitudinal tractive force and pressing force increased with the increase of the communication delay, and the position of the maximum pressing force moved towards the train tail as the delay increased. Moreover, the communication delay had a significant effect on the negative acceleration of the vehicles. For the slave control locomotive, the negative accelerations increased with the increase of delays. For the other vehicles, the change of the delays would cause the fluctuation of negative accelerations. Furthermore, the effects of communication delay on longitudinal impulse were in coincide under different dynamic braking forces in air brake process. In air brake release process, the smaller the dynamic braking force was applied, the more significant effect of communication delay on longitudinal impulse exhibits.
