Pantograph and catenary condition based monitoring through pan-head acceleration.

, 2012
This paper describes a diagnostic system for pantograph and catenary condition based monitoring, based on the measure of collector accelerations. The proposed set-up is cheap and feasibly installable on commercial service trains, with the aim to improve ...

Characterization of Contact Resistance Between Pantograph and Catenary System

, 2012
The static and dynamic contact resistance was studied with different contact pressures and traction currents. The results show that the static contact resistance of pantograph and centenary is decreased when contact pressure and traction current ...

Non-destructive analysis (NDT) of pantograph and catenary interaction

, 2011
In the last decades the development of very high speed trains in railway transportation requires new maintenance strategies. New trolleys equipped with innovative measuring systems have been employed for monitoring overhead lines (catenaries). Using this

Pneumatic Active Control System for Pantograph-catenary interaction

, 2013
Pantograph-catenary interaction is one of the most important items for operation of high speed trains, reliable current collection being the necessary pre-condition to speed up trains. Severe limitations can come from the variability of the contact force acting between the pantograph and the catenary, which can lead to poor current collection or ...

Aerodynamic noise from a train pantograph

, 2014
Many studies have shown that when the speed of high speed trains exceeds around 300km/h, aerodynamic noise becomes the most significant noise source. The pantograph, or current collector, is mounted on the top of the train and is therefore not shielded ...

Study on Model Reference Adaptive Control for Subway Pantographs

Kongzhi Yu Xinxi Jishu
The coupling performance of subway pantographs with catenaries affects the quality of current collection and the safety of trains. The rigidity of these catenaries exhibits periodicity and fluctuations due to factors such as geographical locations ...
