摘要
指出了国内外在列车—桥梁时变系统空间振动计算中存在的不足,并提出了改进办法。根据桥上列车脱轨能量随机分析理论,基于列车-桥梁时变系统空间振动计算模型,对京通线东沟桥上货物列车走行安全性、舒适性及平稳性进行了计算和分析。
The limitations in the spatial vibration calculation of train-bridge time variant system having been conducted both at home and abroad are pointed out, and the improvement for the limitations is accordingly developed. According to the theory of random energy analysis of train derailment on bridge and the calculation model of the spatial vibration of train-bridge time variant system, the calculation and analysis of the safety, comfort and smoothness of a freight train running on Donggou Bridge on Beijing-Tongliao Railway Line are carried out.
