铁路货车转向架关键部件的可靠性与寿命评估方法

Reliability and life assessment method of key components of railway truck bogie

摘要

本论文聚焦铁路货车转向架核心元件(轴承、制动器、摩擦销等）的可用性与耐用性，以实际运行数据为基，借统计分析与生命周期模型开展可靠性分析和寿命评估。鉴于转向架可靠性与维修、材质、运行状况紧密相连，论文为关键元件可用时间评估推导出方法，如轴承用韦氏分布模型、制动器用行为链模型，以此有效评估部件可靠性和寿命，助力优化维护策略、降本增效，对提升转向架部件可靠性和安全性具有重要参考价值。

Abstract

This paper focuses on the availability and durability of the core components of railway truck bogies (bearings, brakes, friction pins, etc.). Based on the actual operation data, it carries out reliability analysis and life assessment based on statistical analysis and life cycle model. Given the bogie reliability and maintenance, material, operating condition is closely linked, the paper for the key components available time evaluation derived method, such as bearing with distribution model, brake behavior chain model, to effectively evaluate the component reliability and life, power optimization maintenance strategy, authors efficiency, to improve bogparts reliability and safety has important reference value.
