| 摘 要： | 为了考察侧风环境下列车能否临靠站台高速安全通过,采用列车空气动力学和列车系统动力学相结合的方法,通过侧风与列车的流固振动分析获得列车姿态的变化;考虑侧风作用下,列车的姿态变化和轨道几何不平顺的影响,分析了侧风环境下,列车临靠站台高速通过时的气动响应.计算结果表明,与无风环境尾车易与站台碰撞不同,在6 m/s侧风环境下,当列车以350 km/h的速度临靠站台通过时,车头前端是离站台最近的位置.

| Abstract: | In order to evaluate whether a train can pass through a platform safely at high speed in cross wind,the air-actuated response in this case was studied with both train aerodynamics and train system dynamics considering the track irregularity and the attitude changes of trains caused by cross wind.The attitude changes were obtained from the analysis of cross wind and train fluid-solid coupling vibration.The results show that,different from that the tailing vehicle is easy to collide with the platform in a no-... |
