Research on Pantograph Defect Classification Based on Vibration Signals [PDF]
Pantograph-based electrical current transmission systems are used in electric traction vehicles. The contact surface between the pantograph and the catenary wire experiences mechanical and thermal effects during the train’s movement.

Simulation and Verification of Effect of Arc Duration on Arc Temperature Based on COMSOL
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 ...

Application of GWO-SVM Algorithm in Arc Detection of Pantograph
High-speed train will produce pantograph arc during the driving process, which is harmful to pantograph-catenary system. In order to reduce pantograph-catenary system damage, a method based on Gray Wolf algorithm to optimize the binary Support Vector ...

Stability analysis of pantograph under frictional force
The frictional force acts to the travelling pantograph head in horizontal direction due to sliding of the pantograph head and contact wire. Therefore, vertical motion of the pantograph head is generated by link mechanism of the pantograph.

Numerical Investigation on Aerodynamic Drag and Noise of Pantographs with Modified Structures [PDF]
It is well known that the pantograph, which works as a complex component of high-speed trains, is an important source of aerodynamic drag and aerodynamic noise of a high-speed train (HST) that can affect HST performance, comfort for passengers, and ...
