Reduction of Pantograph Noise of High-Speed Trains

Journal of Mechanical Systems for Transportation and Logistics, 2010
In order to reduce the pantograph noise that greatly contributes to overall noise, we have developed two types of low-noise pantograph. Further noise reduction was realized by the effects of attenuation of the pantograph noise insulation plate and by using only one pantograph per trainset.

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

Theoretical and Applied Mechanics Letters, 2013
AbstractA 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. Being the catenary a stationary system with a long lifespan it is also less likely to be redesigned and upgraded than the pantographs that fit the train vehicles.

Effect of Pantograph’s Main Structure on the Contact Quality in High-Speed Railway [PDF]

Shock and Vibration, 2021
In general, the electrical energy is provided to the high-speed train through the pantograph-catenary sliding contact. The variation of the dynamic contact force is expected to be small enough to keep the good current collection quality and to extend the
