250 km/h高速铁路轨道不平顺的安全管理
Safety Management of Track Irregularities of 250 km/h High-Speed Railway

摘要:利用根据车辆-轨道耦合动力学思想所建立车辆-轨道垂横耦合模型,在充分考虑多种波长并存的情况 下,仿真计算了250 km/h高速铁路各种轨道不平顺的管理目标值。计算结果与日本和德国高速铁路轨道不平 顺的经验管理目标值基本一致。Abstract:Using the vertical-lateral model of vehicle-track coupling system, which is set up based on the vehicle-track coupling dynamics, and taking the coexistence of manifold wavelengths into account, the management values of various track irregularities in 250 km/h high-speed railway are calculated by simulation. The calculation results are consistent with the management values of the high-speed railway of Japan and Germany on the whole.
