中文摘要：
文中针对高速列车系统动力学数字化仿真平台在系统动力学仿真过程中耦合器和执行机之间数据发送量大、交换频繁而导致的通信中断、通信阻塞、信息丢包等现象，设计并实现了耦合器通信故障的检测和恢复。分布式仿真系统因网络通信故障停止后，该设计通过多次请求、定时检测、信息重传等机制实现了仿真系统停止后接着仿真停止前的状态继续仿真计算，并对仿真系统停止后的仿真状态和仿真结果数据具有一定的保存能力，从而保证分布式仿真系统稳定、可靠的运行。
英文摘要：
Aiming at the phenomenon of communication interruption,communication blocking,information packet loss caused by big data transmission,frequent change between the coupler and execute machine in system dynamics simulation process in the high speed train coupling system dynamics digital simulation platform,designed and realized the coupler communication fault detection and recovery. Dis-tributed simulation system is topped due to the network communication fault,the design through the repeated requests,timing detection, information retransmission mechanism to realize the simulation system is continue to simulation then the state that in front of the simula-tion stop state,and the state of the simulation and the simulation results after the stop of the simulation system have certain ability to save data,so as to ensure the running of distributed simulation system is stable and reliable.
