Assessment of pantograph-catenary interaction in a railway overlap section via a novel optical-based method
(Peer reviewed; Journal article, 2022)Smooth pantograph-catenary contact is essential for regular train operation. However, catenary section overlaps are locations where peak contact forces occur, which significantly affects current collection quality. This ... -
Dynamics of luffing motion of a flexible knuckle boom crane actuated by hydraulic cylinders
(Journal article; Peer reviewed, 2020)In this paper we present a modeling procedure for a flexible knuckle boom crane, which is actuated by hydraulic cylinders and is modeled as a planar multibody system. We propose a convenient framework where both rigid body ... -
Identification of short-wavelength contact wire irregularities in electrified railway pantograph–catenary system
(Peer reviewed; Journal article, 2021)The effect of two common types of short-wavelength irregularities (local imperfections and periodic short-wavelength irregularities) of the railway catenary on the pantograph–catenary interaction performance are studied ... -
A methodology to study high-speed pantograph-catenary interaction with realistic contact wire irregularities
(Peer reviewed; Journal article, 2020)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 ... -
Wind deflection analysis of railway catenary under crosswind based on nonlinear finite element model and wind tunnel test
(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 ...
