摘要：

随着高速列车运行速度的不断提高,列车周围的空气流场在运行过程中发生剧烈变化,产生湍流现象,使列车与周围接触网之间的稳定受到威胁,甚至损坏接触网的结构,影响列车的正常运行。本研究运用有限元分析法对不同风速下的接触网进行数值模拟仿真,计算接触网在列车运行过程中所受到的应力、壁升力以及抖动现象,进而比较不同风速下接触网的空气受流情况。提出的运用有限元分析法解决接触网在不同风速下空气受流的方式,对接触网空气受流问题,具有简便快速准确的特点。

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
