摘要
本文建立了车辆动力分析的空间耦合振动模型,并对模型进行了动力学仿真,分析了轨道高低、轨向和水平不平顺对准高速行车的影响,进而从安全和乘车舒适角度提出了准高速线路轨道不平顺管理的建议值。
The effect of track irregularities in profile,alignment and crosslevel on quasi highspeed train is studied by way of simulation in this paper. A multi-component coupled vibra-tion space model for car system is set up,and the numerical results of dynamic simulation,are investigated.Based on this and the considerations of safety and riding comfort,the allow-able limits for track profile,alignment and crosslevel irregularities are proposed.
