大风作用下高速列车运行安全性研究综述

大风是影响高速列车运行安全性的重要因素,伴随着高速铁路的快速发展,国内外研究者开展了大量有关大风作用下列车运行安全性的研究。对国内外涉及风致安全性的研究进行较全面和系统的阐述,其中,国外的研究以相关国家进行分类;国内的研究主要分为不同工况下高速列车周围流场及列车安全性研究,周围环境对于列车气动特性的影响,风、车、桥耦合研究等3类。介绍大风条件下列车运营规则的现状,分析研究难点,并对今后的发展方向进行展望。

Study Review on Operation Safety of High Speed Train in Gales

Gale is an important factor affecting the operation safety of high speed trains.With the rapid development of high speed railways,the researchers at home and abroad have conducted a lot of studies on the operation safety of trains in gales.This paper expounds the studies on wind-induced safety at home and abroad in a comprehensive and systematic way.Among them,the foreign studies are classified in terms of relevant countries,and the domestics studies are mainly divided into three types,i.e.study on the air flow field around the high speed train and train safety under different working conditions,the effects of the surrounding environment on the aerodynamic characteristics of train,as well as the coupling study of wind,vehicle and bridge.This paper introduces the current status of the operating rules of train under high wind conditions,analyzes the research difficulties,and forecasts the future development orientation.
