Abstract Vibration compensation in track displacement monitoring is explored by using rail image feature points. The key point is to compare the image of the rail to be tested with the image of the standard rail. A downstream section of Metro Line A is selected for real time analysis of image.

Carbon brush wear calculation in marine environment based on temperature field analysis
Abstract In the marine environment, the working environment of the doubly fed wind generator carbon brush and slip‐ring system is complicated, salt spray deposits and seawater erosion affect the temperature field and contact surface friction factor leading to carbon brush wear increase and shortened replacement cycle.

Experimental stand and researches on pantograph-catenary contact force control using chaos theory
Abstract Due to the oscillating behaviour of the pantograph and the catenary during the movement of the locomotive, the contact force changes to wide limits, resulting in electrical sparks with consequences: premature wear of the contact wire, electromagnetic disturbances, energy loss.

Study on electric spark discharge between pantograph and catenary in electrified railway
Abstract The electric spark caused by pantograph‐catenary (PC) electrical contact failure happens frequently, it is a kind of arcing phenomenon which can severely affect the current collection of PC. The theoretical analysis and modelling of PC electric spark are tried.

Pantograph Catenary Contact Force Regulation Based on Modified Takagi-Sugeno Fuzzy Models
In this paper, a new contact force control technique, based on the modified Takagi-Sugeno model and the parallel distributed compensation concept is developed to suppress vibrations between the pantograph and the catenary by regulating the contact force to a reference value, thereby achieving stable current collection.

Structural Health Monitoring Method of Pantograph–Catenary System Based on Strain Response Inversion
Pantograph-catenary system provides electric energy for the subway lines; its health status is essential to the serviceability of the vehicle. In this study, a real-time structural health monitoring method based on strain response inversion is proposed ...

A Study on the Measuring System of Contact Force of Pantograph for the High-Speed Train
The overhead pantograph for the high speed train is a mechanical and electrical part mounted on the train roof to supply the train with electrical power from the catenary system.
