Track Behavior Characteristics Analysis in Curved Track for Tilting Trains

초록

The track performance evaluation in curves of conventional line during the passage of the Korean tilting train was carried out. Moreover, the correlations between train speed and track alignment was reviewed. The parameters of track alignment were determined by field investigation of all curves in conventional line. It was founded that pressure of the rail did exceed the allowable stress when the tilting train speed was over 96km/hr in the curve with radius of 300m. As the radius of curvature is smaller, applied force due to the tilting train becomes larger in the curved track regardless of the construction of the continuous welded rail (CWR). On the while, the variation of applied force on the track corresponding to the cant variation is not so much as expected.
