| 摘 要： | 针对解决列车运输能力局限性的问题,对开行万吨重载列车进行了研究.通过建立列车纵向力模型,主要考虑车钩间隙与空气阻力两个影响因素,利用Matlab仿真的方法研究了车钩的受力情况与规律;在仿真的结果上对重载列车的同步控制性能进行了评价,引入了Markov策略以优化同步无线传输性能;结合1＋1＋1万吨列车的实际试验结果与数据,比较了仿真模拟结果与试验值,研究结果表明,两者基本上吻合,在实际运行线路中加入优化策略是可行的,能够实现对同步控制性能大幅度地优化,为进一步优化长大重载列车的同步控制性能奠定了基础.

| Abstract: | Aiming at the problems of limitation of transportation ability,running heavy haul train was studied.The model of train longitudinal force which mainly involved train couplers gap and air resistance was established to study forces of train couplers by using Matlab.The synchronous control capability was evaluated on the simulation,then the Markov strategy was established to optimize the synchronous wireless transmission.The experimental results and data of 1 ＋ 1 ＋ 1 ten thousand tons train were compared with the simulation results.The results indicate that they are reasonable and it shows that applying optimized strategy in railway lines is feasible.Synchronous control capability of heavy haul train which contained Markov strategy was greatly optimized.Then the foundation of further improving synchronous control capability is built. |
