Abstract
The research status of train derailment is summarized. Major problems existing in current derailment research are pointed out. By applying system dynamics stability concepts, the mechanical mechanism of train derailment is described. The theory of random energy analysis for train derailment is then further expounded and preventive measures for train derailment and a calculation method for an anti-derailment safety coefficient (of train – track time variant system) are introduced. Finally, some train derailment cases are analysed. Six train – track time variant system vibration cases are calculated, four of which derailed and two that did not. The conclusion compares the results of the theoretical analysis with that which actually occurred.
