Friction and Wear Performance of Pantograph-Catenary System in Electrified Railways:State of the Art
摘要
Abstract
For pantograph-catenary contact pairs in electrified railways operating in normal and abnormal states,the friction and wear performance of pantograph strip differentiates in a wear cycle,highlighted by differences in wear rate and wear profile.When abnormal wear occurs,the wear rate of pantograph strip will have a multifold increase or even dozens of times increase,but the wear profile acts differently,revealing partial eccentric wear,wavy wear,and penetrating wear.The similarities and differences in current-carrying friction and wear platforms are summarized for pantograph-catenary systems,as well as the advantages and disadvantages of contact and non-contact detection methods.The influential factors and evolution law are analyzed in view of the structure and parameters,train operation parameters,current-carrying parameters and external environment of pantograph-catenary system.Following above work,the state of the art of pantograph-catenary wear models,including mechanism analysis model and data fitting model,are analyzed extensively,and the prospective direction and development trend are put forward,such as,the equivalent simulation of a pantograph-catenary friction pair in real service under laboratory conditions,online high-precision detection of pantograph-catenary wear performance,simulation and optimization of pantograph-catenary wear performance in complex climatic conditions and multi-physical field coupling,pantograph-catenary wear prediction using big data and intelligent algorithms,intelligent operation and maintenance strategies,and capability maintenance in the whole life cycle.关键词
