An investigation into the aerodynamic characteristics of catenary contact wires in a cross-wind [PDF]
, 2001 An experimental analysis of the aerodynamic characteristics of catenary contact wires is presented. The aerodynamic data obtained were used to calculate the Glauert-Den Harthog criterion for one-dimensional galloping.

Reduced-order modelling of vortex-induced vibration of catenary riser [PDF]
, 2009 A new reduced-order model capable of analyzing the vortex-induced vibration of catenary riser in the ocean current has been developed. This semi analytical-numerical approach is versatile and allows for a significant reduction in computational effort for

An investigation into the mechanical damping characteristics of catenary contact wires and their effect on aerodynamic galloping instability [PDF]
, 2003 Measurement of the damped oscillation of a section of the UK East Coast Main Line (ECML) catenary/contact wire system was undertaken, and the natural frequency and mechanical damping were found to be 1.4Hz and 0.05 respectively. This information was used

Pantograph catenary dynamic optimisation based on advanced multibody and finite element co-simulation tools [PDF]
, 2013 This paper presents recent developments undertaken by the SNCF Innovation & Research Department on numerical modelling of pantograph catenary interaction. It aims at describing an efficient co-simulation process between finite element (FE) and multibody (

Journal of Fluid Mechanics, 2011 AbstractUsing the classical catenary as a motivating example, we use slender-body theory to derive a general theory for thin filaments of arbitrary rheology undergoing large combined stretching and bending, which correctly accounts for the nonlinear geometry of deformation and uses integrated state variables to properly represent the complete ...

The Catenary in History and Applications (La Catenaria nella Storia e nelle Applicazioni)
Science & Philosophy, 2017 The catenary is one of the most common curves; it is, in fact, the shape assumed by a homogeneous and inextensible chain, fixed to the extremities, which is subject only to its own weight.

Simulation and Verification of Effect of Arc Duration on Arc Temperature Based on COMSOL
Machines, 2023 The pantograph–catenary arc of urban rail has the characteristic of high temperature, which directly acts on the surface of the pantograph–catenary system, will seriously ablate pantograph and contact line, and affect the flow of the pantograph–catenary ...
