Electrical Contact Performance and Analysis
Electrical Contact Performance and Analysis is a research topic within Mechanical Engineering. Science Explorer counts 10k research works in it since 1950. 11.1% of them reached the world's top 10% most cited for their field and year.
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.
