Abstract
Metro vehicles bogie system is one of the important components of urban rail train. Its performance largely determines the vehicle running stability and safety. Accurately analyzing the reliability of urban rail train bogie system for urban rail train running stability and security is of great significance. This paper establishes fault tree model through the study found that all of the bottom events occur will cause bogie system failure. This paper is based on the analysis of the fuzzy importance degree according to the reliability analysis. The results show that the air spring breakages, brake failure, wheel tread strip, and flange abrasion of bogie had a greater influence on the performance of the system. This result is similar to actual operation.
