Dynamic Performance Simulation of Overhead Contact System for over 350km/h High-Speed Rail

Abstract

With full development of 350km/h high-speed rail network in China, further research in the key technology of 380km/h or higher super-speed rail system has become crucial. Applying the simulation of pantograph-catenary interaction based on infinite element method, this paper simulated the dynamic performance of pantograph-catenary system for high-tension overhead contact system at over 350km/h. The research findings showed that wave propagation speed can still serve as a brief computing method for the running speed within the range of 350-400km/h. When the running speed reaches 80% of the wave propagation speed or higher, the current-carrying quality of double-pantograph-catenaries system might not satisfy the standard of EN 50367 all the time.
