| 摘 要： | 基于列车桥梁时变系统空间振动计算模型及列车脱轨能量随机分析方法，分别对京山线滦河老桥上行线及下行线货物列车脱轨全过程进行了计算，采用判别列车脱轨的能量增量准则，得出下行线货物列车脱轨，上行线货物列车不脱轨的结论，此结论与实际符合。同时还对引起该桥下行线货物列车脱轨原因进行了分析，认为桥梁横向刚度不够是引起脱轨的主要原因，并指出桥梁横向刚度是保证桥上列车安全运行的主控因素。

| Abstract: | Derailment course of freight train running on the old Luanhe bridge of Jingshan up and down direction line was respectively calculated by the calculation model of special vibration of train-bridge time-variant system and the random energy analysis method of train derailment. Using energy increment criterion, the derailment case of freight train running on down direction line was calculated, and freight train running on up direction line was judged to be not derailed, which correspond to the fact. Meanwhile, the derailment reason of freight train running on down direction line was analyzed. It is pointed that the lack of bridge rigidity is the main reason causing train derailment, and bridge rigidity is the main controlled factor ensuring train's safety running on the bridge. 3 tabs, 6 figs, 7 refs. |
