摘要
运用车辆、轨道耦合大系统思想,将轨道高低、水平、方向和轨距四种不平顺视为平稳的各态历经随机过程,进行了车辆、轨道系统的动力学分析,仿真计算了250 km/h速度的高速铁路轨道不平顺管理的安全目标值。同时利用线路试验和滚动振动台试验探讨我国干线轨道谱与国外典型轨道谱的区别与联系。
On the basis of the coupling thought of vehicle and track is applied, the track vertical profile, cross-level, alignment and gage irregularities are regarded as stationary ergodic Gaussian random processes. The vertical and lateral random vibration of vehicle and track is analyzed; the safe manage limits of high speed railroad track irregularities in the 250 km/h velocity field are calculated; at the same time, the difference and relation of Chinese main track irregularities PSD and overseas typical track irregularities PSD are discussed.
