In this study, in order to clear the mechanism of corrugation development with longitudinal slip, the phenomena were reproduced by experiments using 'corrugation simulator'. The following results were obtained from the detailed analyses of measured experimental data with wavelet analysis and theoretical considerations: 1. The steady state longitudinal slip determines developed corrugation type and wavelength; 2. The short pitch corrugation is developed under low creepage conditions. The corrugation passing frequency is about 1 kHz which is a natural frequency of the bending mode of the wheel axle at the corrugation simulator; 3.The long wavelength corrugation is mainly developed under the relatively large slip condition. The corrugation passing frequency is 50 Hz which is a natural frequency of the vertical mode of the roller rig at the corrugation simulator; 4. By the investigation of the whole process of corrugation, the mechanism which corrugation is developed was explained from wear rate and the phase relation between corrugation profile, contact load and slip; 5. The steady state longitudinal slip effects on wear rate and has an important roll on whether corrugation is growing or decreasing in the developing process of corrugations.
