Computational fluid dynamics-multibody system dynamics bidirectional coupling calculation and flow-induced vibration evaluation of a high-speed pantograph-catenary system

Engineering Applications of Computational Fluid Mechanics
Increasing the speed of a pantograph deteriorates its aerodynamic performance and aggravates the problem of flow-induced vibration, which is not conducive to the stability of the pantograph – catenary system (PCS). Currently, commercial high-speed trains

Numerical study on pantograph raising and lowering in multi-pantograph operation

, 2017
Multi-pantograph operation is a convenient and efficient way to operate railway rolling stock, but the influence between the pantographs makes the system more sensitive and vulnerable than a single-pantograph system.

Fatigue analysis of catenary contact wires for high speed trains [PDF]

, 2011
The fatigue fracture is one of the most critical failures which may occur on the high speed network because it is undetectable and it has a huge impact on traffic disruption.

The Image Detection of Pantograph Slide Based on Yang-shot Mode

机车电传动, 2010
At present, most of the pantograph slide images based on the image processing to detect slide wear are obtained by using overhead mode, but this way has some limitations for some complex arched.

A Reduced Pantograph-Catenary Interaction Model for Efficient Pantograph-Catenary Interaction Dynamic Analysis

The continuous movement of high-speed train results in the pantograph interacting with a long catenary structure. The traditional methods based on the Lagrangian description can only model the whole long catenary structure, which decreases their ...
