Review of Catenary Icing on High‐Speed Railways: Characteristics, Impact and Countermeasures
High VoltageThe pantograph–catenary system (PCS) is the only path for electrified railway trains to acquire energy. Catenary icing during winter is a common natural phenomenon, which usually leads to the deterioration of the current quality and severely affects the ...

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 ...

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.

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 ...

Catenary and Mercator projection
CoRRThe Mercator projection is sometimes confused with another mapping technique, specifically the central cylindrical projection, which projects the Earth's surface onto a cylinder tangent to the equator, as if a light source is at the Earth's center. Accidentally, this misconception is rather close to a truth.

Quality and Reliability Engineering International, EarlyView.ABSTRACT Electric multiple unit (EMU) trains, widely used in modern railway transportation, use Nickel–Cadmium (Ni–Cd) batteries to power auxiliary systems on board, including lighting, ventilation, control electronics, and emergency systems. These batteries are often connected in parallel to ensure a wider power supply range for electrical loads that ...
