DOI: 10.1016/j.mechmachtheory.2020.103940
Abstract: Abstract In high-speed rail operations, the irregularity of the overhead system is a typical disturbance that affects the pantograph-catenary interaction performance. The existing methods, which treat the contact wire irregularities as hard spots, overestimate the… read more here.

DOI: 10.1016/j.wear.2020.203401
Abstract: Abstract The sliding contact between the pantograph and catenary allows the correct operation of electric trains. However, this contact induces wear on both the components involved in the process, namely the contact strip on the… read more here.

DOI: 10.1109/access.2019.2955753
Abstract: The contact wire support (CWS) is an important catenary component that maintains the contact wire height and stagger. The direct impact of the pantographs makes the CWS a vulnerable part of the catenary. Recently, automatic… read more here.

DOI: 10.1109/tim.2020.2987457
Abstract: 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 pointwise stochastics of CWI,… read more here.
