Reliability Analysis of Tram Electro-mechanical Braking System Based on Fuzzy Fault Tree

Abstract

Objective The electro-mechanical braking system architecture of tram is different from that of the traditional braking system, so it is necessary to analyze the system safety and make targeted improvement to its weak links. Method Using fuzzy fault tree method can obtain the triangular fuzzy number of the top event occurrence probability through analysis of the test data, and then obtain the fuzzy importance of each bottom event. According to the fuzzy importance of the bottom events, the weak links of the system are analyzed and improved to realize the fault prevention. Result & Conclusion By analyzing the reliability of the tram electro-mechanical braking system based on fuzzy fault tree, the safety of the system weak links can be improved, and the corresponding improvement measures be put forward, helpful for improving the safety and reliability of the electro-mechanical braking system.
