Proceedings of the Institution of Mechanical Engineers, Part F: Journal of Rail and Rapid Transit, 2018
This paper deals with the design, development and testing of a novel force transducer based on fibre-optic technology, for the measurement of contact force between a pantograph and an overhead line. Due to the particular application, in which part of the measurement chain is at high voltage and part is at ground potential, fibre-optic technology has ...

Application of new optical load cells for in-line measurement of pantograph-catenary contact force
SPIE Proceedings, 2013The contact force between pantograph and catenary is a parameter needed to evaluate the quality of the dynamic interaction of the two systems. The in-line measurements of this parameter have always been very hard due to the particular work condition of pantograph and catenary.

The high-speed train is typically powered by the catenary wire suspended from poles or towers along the rail. An important issue of the high-speed train's power supply is how to set the precise contact force between the pantograph and catenary wires in real time.

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
2003The 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

An optical fibre set-up to monitor contact force in pantograph-catenary system
2007The 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 ...
