A novel design of a compact S-shaped balance with FBG sensors for the pantograph-catenary contact force measurement

SPIE Proceedings, 2012
The measurement of the contact force between pantograph and catenary in railway engineering has been carried out in the past with conventional electrical load cells. This study evaluates the use of fiber Bragg gratings (FBG) sensors, so that electrical insulation of the load cells, placed on high voltage parts, is obtained by means of the fiber optic

Application of the EKF to the estimation of contact forces in pantograph-catenary system

2003
The knowledge of the contact forces exchanged between pantograph and catenary (OverHead Line, OHL), together with the contact loss condition, is a very important mean to assess the overall performance of current collection. From the knowledge of the contact force it is possible to assess the dynamic performance of the pantograph-OHL system, moreover it

A temperature-compensated fiber Bragg grating sensor system based on digital filtering for monitoring the pantograph–catenary contact force

Proceedings of the Institution of Mechanical Engineers, Part F: Journal of Rail and Rapid Transit, 2018
Optical sensors based on fiber Bragg gratings have become an important type of sensing element for strain measurements. In this study, fiber Bragg grating strain sensors and corresponding reference temperature sensors were integrated into a pantograph strip.

An optical fibre set-up to monitor contact force in pantograph-catenary system

2007
The use of fibre optics for the detection of contact loss and the estimation of contact force between pantograph and catenary is experienced in a laboratory test bench. Preliminary results show the capabilities of this measurement system with respect to traditional measurement system for contact force, with the advantage of a negligible impact on the ...
