doi:10.11985/2019.04.008

Abstract

Abstract:

With the continuous improvement of the running speed of high-speed trains, the air flow field around the train changes drastically during the operation, causing turbulence, which makes the stability between the train and the surrounding contact net threatened, and even damages the structure of the contact net, affecting The normal operation of the train. In this study, the finite element analysis method is used to simulate the contact nets under different wind speeds, and the stress, wall lift and jitter of the contact network during train operation are calculated, and the air flow of the catenary under different wind speeds is compared. The finite element analysis method proposed is to solve the problem that the contact net is subjected to air flow at different wind speeds, and it is simple, fast and accurate for the problem of air flow in the contact network.

Key words: High-speed train, catenary, numerical simulation, air flow, finite element analysis
