{"cited_by_count":96056,"description":"This cluster of papers focuses on the dynamics and performance of pantograph-catenary systems in railway electrification. It covers topics such as wear prediction, sliding wear behavior, arc erosion, influence of electrical current, and the development of new electrical contact materials. The research also delves into the impact of aerodynamic forces, temperature, and various parameters on the pantograph-catenary interaction for high-speed trains.","display_name":"Electrical Contact Performance and Analysis","domain_id":"3","external_ids":{"openalex":"https://openalex.org/T12371","wikipedia":"https://en.wikipedia.org/wiki/Pantograph_(transport)"},"field_id":"22","id":"T12371","keywords":[{"display_name":"electrical contacts","id":"electrical-contacts","score":0.4834,"url":"https://openalex.org/keywords/electrical-contacts"},{"display_name":"electrical connectors","id":"electrical-connectors","score":0.4053,"url":"https://openalex.org/keywords/electrical-connectors"},{"display_name":"pantograph","id":"pantograph","score":0.5279,"url":"https://openalex.org/keywords/pantograph"},{"display_name":"overhead contact line","id":"overhead-contact-line","score":0.4573,"url":"https://openalex.org/keywords/overhead-contact-line"},{"display_name":"contact materials","id":"contact-materials","score":0.4461,"url":"https://openalex.org/keywords/contact-materials"},{"display_name":"electrical contact materials","id":"electrical-contact-materials","score":0.6904,"url":"https://openalex.org/keywords/electrical-contact-materials"},{"display_name":"catenary","id":"catenary","score":0.2594,"url":"https://openalex.org/keywords/catenary"},{"display_name":"arc erosion","id":"arc-erosion","score":0.6186,"url":"https://openalex.org/keywords/arc-erosion"},{"display_name":"contact wear","id":"contact-wear","score":0.5984,"url":"https://openalex.org/keywords/contact-wear"},{"display_name":"current collection","id":"current-collection","score":0.4164,"url":"https://openalex.org/keywords/current-collection"},{"display_name":"connector testing","id":"connector-testing","score":0.691,"url":"https://openalex.org/keywords/connector-testing"},{"display_name":"contact wire","id":"contact-wire","score":0.7128,"url":"https://openalex.org/keywords/contact-wire"},{"display_name":"pantograph-catenary interaction","id":"pantograph-catenary-interaction","score":0.9015,"url":"https://openalex.org/keywords/pantograph-catenary-interaction"},{"display_name":"pantograph-catenary system","id":"pantograph-catenary-system","score":0.8583,"url":"https://openalex.org/keywords/pantograph-catenary-system"},{"display_name":"overhead contact system","id":"overhead-contact-system","score":0.6158,"url":"https://openalex.org/keywords/overhead-contact-system"},{"display_name":"contact erosion","id":"contact-erosion","score":0.451,"url":"https://openalex.org/keywords/contact-erosion"},{"display_name":"silver contacts","id":"silver-contacts","score":0.3414,"url":"https://openalex.org/keywords/silver-contacts"},{"display_name":"contact reliability","id":"contact-reliability","score":0.4749,"url":"https://openalex.org/keywords/contact-reliability"},{"display_name":"carbon brushes","id":"carbon-brushes","score":0.609,"url":"https://openalex.org/keywords/carbon-brushes"},{"display_name":"crimp contacts","id":"crimp-contacts","score":0.9093,"url":"https://openalex.org/keywords/crimp-contacts"},{"display_name":"contact degradation","id":"contact-degradation","score":0.4692,"url":"https://openalex.org/keywords/contact-degradation"},{"display_name":"switch contacts","id":"switch-contacts","score":0.5924,"url":"https://openalex.org/keywords/switch-contacts"},{"display_name":"relay contacts","id":"relay-contacts","score":0.6565,"url":"https://openalex.org/keywords/relay-contacts"},{"display_name":"connection elements","id":"connection-elements","score":0.3234,"url":"https://openalex.org/keywords/connection-elements"},{"display_name":"sliding electrical contacts","id":"sliding-electrical-contacts","score":0.6879,"url":"https://openalex.org/keywords/sliding-electrical-contacts"}],"legacy_keywords":["Pantograph-Catenary Interaction","Electrical Contact Materials","Wear Prediction","Dynamic Performance","Railway Current Collectors","Sliding Wear Behavior","Arc Erosion","High-Speed Trains","Electromagnetic Valve Actuators","Passive Intermodulation"],"openalex_id":"https://openalex.org/T12371","source_created_date":"2024-01-23T15:27:14","source_updated_date":"2026-10-17T03:02:00","subfield_id":"2210","url":"/topics/T12371","works_api_url":"https://api.openalex.org/works?filter=topics.id:T12371","works_count":28474,"label":"Electrical Contact Performance and Analysis","provider":"openalex","revision":"642af64f257af13e","taxonomy_revision":"f050b5d4780b1289","title":"Electrical Contact Performance and Analysis","kind":"topic-directory","aeo_cohort":"topic-directory","catalogue_revision":"f050b5d4780b1289","numeric_address":"38350966789636857","address_version":"morton4x16-v1","coordinates":[3,22,2210,12371],"answer_status":"Directory metadata; local answer requires separate source review","truth_status":"Subject descriptor, not a factual answer or a demonstrated knowledge gap","reviewed_answer":null}
