Bayesian Network-Based Reliability Analysis of High-Speed Train Bogie System

摘要

The events in the fault tree of CRH2 high-speed train bogie system are regarded as nodes in Bayesian network (BN) based on the relationship between the fault tree and the BN. The bogie system is simulated based on BN with improved expectation maximization algorithm (EM). The weakness of the bogie system can be found through the calculation of the fault probability and the causation analysis. It provides the theoretical basis for drawing up the maintenance project and troubleshooting the system, and helps to make the maintenance decision.
