Abstract

When the high-speed train runs in the track near the electric shield and the protective wall, the edge of the electric shield is less than 3.5m away from the high-speed train, so when the high-speed train passes the electric shield and the protective wall, it will produce a huge air pressure difference between the front and back of the electric shield. The flow field finite element analysis software Fluent was used to analyze the air pressure on the electric shield when CRH3 EMUS passed the electric shield at different speeds, and the distribution law was found, which provided a reference for analyzing the structural mechanical characteristics of the electric shield and the protective wall.
