Abstract

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.
