1203 WIND TUNNEL EXPERIMENTS ON THE CONTROL OF THE LEE SIDE VORTEX OF HIGH-SPEED TRAINS

抄録

At cross wind conditions trains are subjected to strong moments, lift and side forces which reduce the stability of the vehicle. The cross wind sensitivity of trains is a safety relevant topic and train manufacturers are required to meet safety criteria defined in various national and international regulations. In an ongoing research project the lee-side vortex, sometimes called "delta vortex", which contributes to the critical rolling moments, is investigated in order to find methods to reduce its strength.
