RESEARCH ON SERVICE SIMULATION MODELING AND CALCULATION METHOD OF HIGH-SPEED TRAIN

  • 摘要: 高速铁路的出现, 使得轮轨交通技术达到更高的层次.速度提升不仅对列车的牵引动力与动力学性能提出更高要求. 而且,列车与线路、气流等运行环境的耦合作用加剧,并直接影响到了列车的运行品质和安全性. 在高速列车发展初期,研究关注的是如何保证高速列车能高速、平稳和安全运行. 随着运行速度的提高,系统间耦合加强, 服役模拟也越来越受到重视. 而今天,高速列车的服役模拟、健康管理与故障预警成为研究热点,掌握系统全局动态行为、了解微观局部振动是车辆系统动力学研究的方向.本文以高速列车服役模拟为需求, 提出基于循环变量法的长编组列车建模与计算方法,实现任意列车编组的仿真, 得到不同编组位置车辆的服役状态;提出滑移窗口的轨道建模与车线耦合计算方法,得到列车在任意长线路上运行的服役状态; 提出基于时变参数的长期服役计算方法,实现列车在不同服役状态与服役时间的服役模拟. 因此, 基于本文提出的模拟方法,能够实现列车在不同寿命阶段的服役模拟, 而且还可以应用于高速磁浮列车,甚至未来超高速真空管道磁浮列车.
