The pantograph-catenary arc test system for high-speed railways
High speed electric multi units (EMU) get power through pantograph-centenary electrical contact. As the EMU running velocity increases, rail surface irregularities, undulations of the catenary and vibrations of the pantograph head cause the status of ...

Review of Catenary Icing on High‐Speed Railways: Characteristics, Impact and Countermeasures
ABSTRACT The pantograph–catenary system (PCS) is the only path for electrified railway trains to acquire energy. Catenary icing during winter is a common natural phenomenon, which usually leads to the deterioration of the current quality and severely affects the operational safety of trains.

ABSTRACT As the ‘main blood vessel’ of the traction power supply system for high‐speed trains, the ‘wheel‐rail’ coupling grounding reflux system provides the vital channel to send traction current back to terrestrial substations; meanwhile, the rail track also plays a role in transmitting the train's occupancy signal to the control system. An insulated

Introduction of variability in pantograph-catenary dynamic simulations [PDF]
Currently, pantograph-catenary dynamic simulations codes are mainly based on deterministic approaches. However, the contact force between catenary and pantograph depends on many key parameters that are not always quantified precisely.

Abstract This technique describes a scanner‐agnostic digital workflow for generating dynamic mandibular motion from static virtual interocclusal records using a custom artificial intelligence (AI) algorithm and user interface. Virtual records of mandibular positions, including maximum intercuspation, protrusion, and lateral excursions, were captured ...
