K-Step Fault Propagation Method for High-Speed Train System

Abstract

The research on the fault propagation path has become a hot spot in the field of the operation of the high-speed train system. First, the failure propagation network of the high-speed train system is constructed based on network theory and system structure. Second, the K-step fault propagation method is proposed to study the impact of the system topology on the fault propagation according to the failure propagation network. Finally, the proposed method is applied to analyse the process of fault propagation for the bogie system. The results show that the paths of the fault propagation for bogie system obtained by our method agree with the ones in reality. This work may be helpful for the maintenance and the optimal design of high-speed train system, which inspires the following works concerning the reliability and the safety.
