Contact Wire Irregularity Stochastics and Effect on High-speed Railway Pantograph-Catenary Interactions
(Peer reviewed; Journal article, 2020)In high-speed rail operations, contact wire irregularity (CWI) in a catenary is a common disturbance to the pantograph-catenary interaction performance, which directly affects the quality of current collection. To describe ... -
The Effects of Spatially Distributed Damping on the Contact Force in Railway Pantograph-Catenary Interactions
(Peer reviewed; Journal article, 2021)According to field measurements, the damping ratio of a railway catenary varies along the span length and shows an inherent uncertainty. In numerical simulations, it is common to assume a constant damping ratio. Herein, a ... -
An Investigation on the Current Collection Quality of Railway Pantograph-catenary Systems with Contact Wire Wear Degradations
(Peer reviewed; Journal article, 2021)In railway pantograph-catenary systems, the contact surfaces undergo wear in long-term operations, directly affecting interaction performance and potentially deteriorating the current collection quality. The effect of ... -
Vibration Measurement and Wave Reflection Analysis in an Electrified Railway Catenary Based on Analytical Methods
(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 ...
