Abstract：Research purposes:It is great important to do the study on the risk classification ofmaximum instantaneous wind velocity for the safety of train running on passenger dedicated line. This paper studies themaximum instantaneous wind velocity and strongwind direction for the purpose ofoffering the scientific basis forworking out the technical safety standard for train running on passenger dedicated line in strongwindyweather.
Research conclusions:The study results show thatboth the overturning risk degree ofhigh-speed train and the angle between railway line and wind direction have made remarkable impacts on the safety of train running on passenger dedicated line. Based on the maximum instantaneous wind velocity occurring for one time in two years, the train is forbidden to run asV2_max> 30. 0 m/s, the train speed is limited as 30. 0 m/s[V2_max[20 m/s, and the train speed can be returned to normal asV2_max[15. 0 m/s. W ithmaximum instantaneouswind velocitymentioned above, a direct estimation index of safety and risk degree for train running on passenger dedicated line can be obtained.
