摘要
基于时速400 km中国标准化动车组的动力学参数,利用SIMPACK软件建立动力学模型,模拟列车在无风、“中国帽”横风激扰、列车交会以及通过隧道等状态下的运行平稳性,以便支撑动车组的设计工作。研究表明:在无风、两列车交会运行以及通过隧道的状态下,车速对列车横向平稳性的影响最大;在“中国帽”横风激扰的状态下,车速对列车横向平稳性以及乘坐舒适度的影响较大;在无风、横风激扰以及通过隧道的状态下,随着车速的增大,头车、中间车和尾车的平稳性以及乘坐舒适度都在增大。
Based on the dynamic parameters of Chinese standardized EMU with a speed of 400 kilometers per hour,the dynamic model is established by SIMPACK software,and the smooth running of the train in the state of no wind,“Chinese hat”crosswind disturbance,train rendezvous and through the tunnel is simulated,so as to support the design work of the EMU.The results show that in the state of no wind,the intersection of two trains and the passage of tunnels,the speed of the train has the greatest impact on the lateral stability of the train.In the state of“Chinese hat”crosswind agitation,the train speed has a greater impact on the lateral stability of the train and riding comfort.In absence of wind,with crosswind disturbance and when passing through tunnel,the smoothness of head,middle and tail cars and the riding comfort increase with the increase of train speed.
