Assessment of the Current Collection Quality of Pantograph-Catenary with Contact Line Height Variability in Electric Railways
Song, Yang; Duan, Fuchuan; Wu, Fanping; Liu, Zhigang; Gao, Shibin (Peer reviewed; Journal article, 2021)The numerical tools are widely used to facilitate the design of the railway catenary. Only radical results are obtained as the current assessment is generally performed without any practical errors. In this paper, the most ... -
Development of steady arm damper for electrified railway overhead contact line with double pantographs based on numerical and experimental analysis
Chu, Wenping; Song, Yang; Duan, Fuchuan; Liu, Zhigang (Peer reviewed; Journal article, 2021)To improve the carrying capacity, double pantographs are normally used to collect the electric current from the catenary. The mechanical wave excited by the leading pantograph affects the contact of the trailing pantograph ... -
A siamese network-based non-contact measurement method for railway catenary uplift trained in a free vibration test
Duan, Fuchuan; Liu, Zhigang; Zhai, Donghai; Rønnquist, Nils Erik Anders (Peer reviewed; Journal article, 2020)The vibration of the catenary that is initiated by the passing pantograph has a direct influence on the pantograph–catenary contact performance. Monitoring the dynamic uplift of the catenary can help inspectors to evaluate ... -
Study on electric spark discharge between pantograph and catenary in electrified railway
Zhou, Hongyi; Duan, Fuchuan; Liu, Zhigang; Chen, Long; Song, Yang; Zhang, Yexin (Peer reviewed; Journal article, 2022)The electric spark caused by pantograph-catenary (PC) electrical contact failure happens frequently, it is a kind of arcing phenomenon which can severely affect the current collection of PC. The theoretical analysis and ... -
Validation and Analysis on Numerical Response of Super-High-Speed Railway Pantograph-Catenary Interaction Based on Experimental Test
Jia, Yang; Song, Yang; Lu, Xiaobing; Duan, Fuchuan; Liu, Zhigang; Chen, Ke (Peer reviewed; Journal article, 2021)The numerical tools can be used to facilitate the design of the railway pantograph-catenary system. The validation of the current numerical results is mostly performed at a speed slower than 350 km/h. This paper aims at ... -
Vibration Measurement and Wave Reflection Analysis in an Electrified Railway Catenary Based on Analytical Methods
Duan, Fuchuan; Liu, Zhigang; Song, Yang; Derosa, Stefano; Rønnquist, Anders; Zhai, Donghai (Peer reviewed; Journal article, 2021)The wave propagation property of the catenary directly affects the pantograph–catenary interaction performance. Specifically, wave reflection and transmission occurring at waveguide discontinuities, particularly at dropper ...
