Abstract

For ensuring the stable train operation, it is important to estimate accurately the aerodynamic forces acting on a train vehicle. In this study, the aerodynamic forces acting on a vehicle model standing on a coast configuration model were measured by wind tunnel experiments. The coast configuration model consists of an embankment on a windward side and a cutting on a leeward side. The coast configuration model was so prepared that the cutting height, the gradient of slope of the cutting and the distance from the vehicle to the cutting can be varied. The aerodynamic forces acting on the vehicle model standing on the coast configuration model were compared with the aerodynamic forces acting on vehicle standing on the normal embankment. The aerodynamic force coefficients were smaller as the cutting was higher, steeper and nearer the vehicle. This showed the possibility that the cutting reduced aerodynamic forces acting on vehicle standing on the coast configuration than that acting on vehicle standing on normal embankment.
