Abstract The operational safety characteristics of trains exposed to a strong wind have
caused great concern in recent years. In the present paper, the effect of the strong gust
wind on a high-speed train is investigated. A typical gust wind model for any wind angle,
named “Chinese hat gust wind model”, was first constructed, and an algorithm for
computing the aerodynamic loads was elaborated accordingly. A vehicle system dynamic
model was then set up in order to investigate the vehicle system dynamic characteristics.
The assessment of the operational safety has been conducted by means of characteristic
wind curves (CWC). As some… More >
