Abstract: <P>PROBLEM TO BE SOLVED: To provide a damage state detection method and a device of a wheel tread capable of automatically detecting accurately flat, exfoliation and heat crack of a wheel tread.  <P>SOLUTION: Vibration of a track when a rolling stock is running is detected relative to each wheel by a vibration detection device, and a short-time effective value having a short integration time and a long-time effective value having a long integration time are operated from a detected signal. For example, the integration time of the short-time effective value is 100-300 mm in terms of the moving distance of the wheel tread, and the integration time of the long-time effective value is the perimetric length in terms of the moving distance of the wheel tread. The state of the wheel tread is detected, classified by the damage kind, for example, the independent flat and the heat crack, based on the relative relation between the short-time effective value and the long-time effective value as shown in the graph on figure. Since the heat crack can be discovered early and coped with, the amount of reconditioning of the wheel can be reduced.  <P>COPYRIGHT: (C)2004,JPO&NCIPI
