STATICAL CONSIDERATION FOR RAILWAY VEHICLE OVERTURN DUE TO LATERAL WINDS

In an attempt to speed up trains on the narrow-gauge lines to 130 km/h, the lateral wind forces acting on the train were investigated as one of the factors concerning the speed restriction on heavily curved sections. First, models of the lightest passenger cars were submitted to wind-tunnel experiment. Results of the experiment were then analysed to calculate the critical wind speed for overturn of the vehicle. It was revealed that the acting drag force and the position of the aerodynamic centre in a vehicle were much more influential to overturn than the suspension stiffness.
