Optimization of high-speed railway pantographs for improving pantograph-catenary contact [PDF]

, 2013
A crucial system for the operation of high-speed trains is the pantograph catenary interface as it is the sole responsible to deliver electrical power to the train.

Study on the Length of the Effective Vibration Area of the Catenary in a Pantograph–Catenary Interaction System

Applied Sciences
The effective vibration area includes most of the catenary vibration caused by pantograph–catenary interactions and is the basis of the real-time catenary model for hardware-in-the-loop simulation.

Research on the Mechanical Mechanism and Detection Technology of Abnormal Wear and Contact Wire Disengagement in Rigid Overhead Contact Systems

Machines
The disengagement of contact wires in rigid overhead contact systems (ROCS) is a critical hazard to urban rail transit, potentially causing pantograph–catenary collisions, wire breakage, and large-scale catenary failures.

Unsteady aerodynamic forces on a railway pantograph and their influence on pantograph-catenary dynamic interaction [PDF]

, 2018
Pantograph and overhead line aerodynamics is responsible for affecting the con-tact force between the pantograph and the contact wire, both in terms of average value and dy-namic variation. Stationary forces acting on pantograph components can change the

The pantograph lift measurement method in overhead catenary system

Nihon Kikai Gakkai ronbunshu
Condition monitoring technology has advanced remarkably in recent years in various areas, including railways. Since the overhead catenary system and the pantograph in railway does not have enough redundancy, failures of the overhead catenary system or ...
