Static and Dynamic Analysis of Conductor Rail with Large Cross-Sectional Moment of Inertia in Rigid Catenary Systems
Feng, Xiaohe; Gao, Shibin; Song, Yang; Hu, Zeyao; Chen, Long; Liang, Tao (Peer reviewed; Journal article, 2023)The rigid catenary system is widely used in tunnels to power electric trains via contact with a pantograph. Due to gravity, the contact wire normally has a sag that may affect the dynamic interaction performance with a ... -
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 ... -
Wind deflection analysis of railway catenary under crosswind based on nonlinear finite element model and wind tunnel test
Song, Yang; Zhang, Mingjie; Øiseth, Ole Andre; Rønnquist, Anders (Peer reviewed; Journal article, 2022)This paper evaluates the railway catenary's wind deflection under crosswind based on wind tunnel experiments and a nonlinear finite element model. A catenary model is constructed based on the absolute nodal coordinate ...
