摘要
转向架是机车车辆的关键子系统之一,对保证列车的运行性能和服役安全具有重要的作用。随着列车运行速度的提高,轮轨之间的动态相互作用加剧,导致轮对、轴箱轴承、齿轮传动系统、牵引电机等转向架关键运动部件的运行工况十分恶劣,故障时有发生,危及行车安全。针对转向架关键运动部件的动力学行为和故障诊断,国内外学者开展了大量的研究工作。首先,从动力学模型、故障机理分析两个方面总结了转向架关键运动部件的研究现状。其次,梳理了转向架关键运动部件故障诊断中常用的信号处理和机器学习方法。最后,面向智能运维的工程需求,对当前研究存在的问题和发展趋势进行了总结和展望。
Bogie is one of the most key systems of the railway locomotives and vehicles,which plays an important role in ensuring the service performance and safety of trains.With the increase of speed,the dynamic interaction between the wheel and rail will be intensified.The harsh operating conditions of the bogie often result failures in such key rotating components as wheels,axlebox bearings,gear transmission systems and traction motors.In order to ensure the train’s safety,the research on dynamic and fault diagnosis of key rotating components in bogies has received widespread attention.Firstly,the current researches on dynamic model and fault mechanism analysis are summarized.Then,the commonly used signal processing and machine learning methods for fault diagnosis are reviewed.Finally,the existing problems and prospects facing the future application scenarios for intelligent operation and maintenance are given.
