This paper deals with the experimental study of the growing process of the corrugation on a flexible truck. The flexible track/wheel corrugation simulator was made in the laboratory. A rolling wheel driven with constant velocity runs around on the track. From an experiment results it is clarified that the wave length of the corrugation with the natural frequency of the system depends on the position of the disturbance on the track. It is also pointed out that the contact rigidity, flexible track and a little slip should be considered as the main factor of the corrugation development.
