Journal ArticleDOI
Nonlinear analysis of wind-induced vibration of high-speed railway catenary and its influence on pantograph–catenary interaction
TL;DR: In this paper, the aerodynamic coefficients of the contact/messenger wire are calculated through computational fluid dynamics, and the wind-induced vibration response of catenary is analyzed with different wind speeds and angles.
Journal ArticleDOI
Active control of contact force for high-speed railway pantograph-catenary based on multi-body pantograph model
TL;DR: In this paper, a multi-body model of pantograph is established, and two configurations of installing actuators on a multibody pantograph are presented, in combination with a nonlinear finite element model of catenary, the control performance is evaluated through several numerical simulations.
Journal ArticleDOI
Nonlinear modelling of high-speed catenary based on analytical expressions of cable and truss elements
TL;DR: In this paper, a modeling method based on the analytical expressions of nonlinear cable and truss elements is proposed for solving the initial equilibrium state of a high-speed catenary system.
Journal ArticleDOI
Detection of Contact Wire Irregularities Using a Quadratic Time–Frequency Representation of the Pantograph–Catenary Contact Force
TL;DR: Based on the characteristics of quadratic TFRs of PCCF signals, a detection and localization approach for contact wire irregularity is proposed in this paper and results indicate that the different forms of contact wire irregularities could be effectively detected and localized with meter accuracy using the Zhao-Atlas-Marks distribution.
Journal ArticleDOI
Wave propagation analysis in high-speed railway catenary system subjected to a moving pantograph
TL;DR: In this paper, the Fourier transform is exploited to find out the solution of the governing equation of the tensioned cable, whose vertical deflection is assumed as the superposition of two waves propagating to opposite sides.
