Review of Perspectives on Pantograph-Catenary Interaction Research for High-Speed Railways Operating at 400 Km/h and Above

In this article, we comprehensively examine the ongoing research concerning the interaction between pantographs and catenaries, a vital aspect in ensuring uninterrupted electricity supply to trains. Future perspectives for future studies to ensure satisfactory performance at 400 km/h and above are preliminarily explored. Initially, this article provides an overview of the current design and assessment system. A systematic survey on the numerical modeling of pantograph-catenary interaction is conducted. The applicability of current assessment quantities to speeds of 400 km/h and above is preliminarily investigated with a numerical model. The potential of optimizing parameters for improving interaction performance is also explored at this speed level. This article further reviews and preliminarily analyses the effects of common disturbances, such as geometric deviation and aerodynamics, on the pantograph-catenary interaction performance at 400 km/h and above. To prolong the expectancy life of the system, this article also reviews contact wire wear prediction models and discusses their potential application at 400 km/h and above. Overall, this article offers insights into the current state of research on pantograph-catenary interaction for high-speed railways and proposes future directions for improving the system to ensure optimal performance at speeds of 400 km/h and above.
