ON THE PERFORMANCE OF THE RAIL FASTENING DEVICE FOR THE SHARP-CURVED, STEEP-GRADED TRACK

In order to examine the performance of rail fastening device Type 6 designed for PC sleepers used in the sharp-curved, steep-graded section where a severe load condition is assumed, and to make clear the distribution of train load on sharp curve, the lateral wheel force and wheel load, stress of spring clip and rail inclination angle were measured in the field test. These measured results were used for the examination of the fatigue limit of spring clip, the relationship between the lateral wheel force and stress of string clip and the distribution of lateral wheel force.
