Abstract
The authors have performed the numerical modelling of aerodynamic loads on a high-speed train running on a viaduct and evaluated the stability of a train based on the minimum load pressure on the wheel under the combined effects of crosswind and inertial air pressure (known as drift). The distribution of air pressure on the surface of train body elements in areas of overpressure and rarefaction was mapped out. The study has identifi ed the combinations of aerodynamic impacts under which the loads on bogie wheels may decrease to unacceptable levels and established the maximum speed limits for varying aerodynamic loads that arise on coastal railway lines under stormy weather
