MEASUREMENT OF TRACK SPRING CONSTANT AND ATTENUATION COEFFICIENT

The movement of rails under passage of a train is attributable to the actions of the track spring system. This spring constant and a vibration attenuation coefficient have roles in riding characteristics of trains, in track deterioration and in generation of noises and vibration. This report suggests a method of obtaining a spring constant by a wheelset drop test and deals with calculation of these indices by interpreting other data.
