摘要
Abstract
This paper proposed an assessment model for heavy-haul contact lines based on the causal Bayesian network to solve the problem that existing studies have not fully considered the complex causal relationship between risk factors and consequences.Firstly,risk factors such as climatic conditions,vehicle loads,and equipment failures were identified via historical data analysis.Then,a causal network for risk propagation was constructed by combining the contact line fault tree and the failure mode and effect analysis(FMEA)method to clarify the conditional probability relationship between the risk factors.Additionally,reverse inference was carried out by adopting the Bayesian network to identify key risk nodes and causal chains.Finally,the risk was evaluated based on the actual operation data.The results show that the proposed method can not only analyze the direct risk effect,but also reveal the potential causal paths,thus improving the assessment accuracy and reliability,and providing references for railway operation and maintenance.关键词
