摘　　要：在转向架设计阶段,转向架系统的安全性和可靠性评估是保证其生产质量、安全稳定运行的重要前提。本文根据转向架各部件的受力情况,同时考虑各部件的劣化程度和机能相关性,提出了转向架系统的随机流网络模型。最后,提出了一种基于最小割集的方法来评估轨道列车转向架系统的可靠性。本文的研究可为转向架系统的设计提供一种具有支持性的指导和实用方法,有利于转向架系统的高效运作和维护。In the bogie design stage,the safety and reliability evaluation of bogie system is an important prerequisite to ensure its production quality,safe and stable operation.In this paper,a stochastic flow network model of bogie system is proposed according to the force on each component of the bogie,considering the deterioration degree and functional correlation of each component.Finally,a method based on the minimum cut set is proposed to evaluate the reliability of the bogie system of rail trains.This paper can provide a supportive guidance and practical method for the design of bogie system,which is conducive to the efficient operation and maintenance of bogie systems.
