A METHOD FOR MEASURING SPRING AND DAMPING CONSTANT OF TRACK

The author proposes a method for determining the spring coefficient of the spring system of the track, the vibration attenuation coefficient, and the contact spring coefficient between the wheel axle and the rail utilizing a wheel axle dropping test. The results obtained based on existing data are described. In this work, a model was set up for the spring system of track, taking note of the form of the impact force generated by the dropping of the wheel axle and its characteristics. A theoretical analysis was conducted with the model, and it has been found that by drawing on the existing data, it is possible to calculate the spring co-efficient, the diminution coefficient,and the contact spring co-efficient between the wheel axle and the rail, which are characteristic values of the spring system of the track.
