【Abstract】 This paper provided an overview of the research on dynamic simulation between pantograph and catenary and the status of its applications,and looked into the future development of dynamic simulation of pantograph and catenary system.Existing pantograph-catenary dynamic simulation methods mainly include virtual simulation and semi-virtual semi-physical simulation.The establishment of pantograph-catenary simulation model mainly depends on continuous equation direct solution method,continuous equation discrete method and direct discrete method.To reduce vibration and prolong lifespan of pantograph and catenary system,simulation will be further developed in optimizing structure of pantograph and catenary,active control of pantograph,and failure recognition of catenary.Finally,the deficiency in current simulation of pantograph and catenary system was analyzed and some suggestions were proposed for future research.更多还原
