Abstract
The self-generation of corrugations is observed on rolling surfaces such as rail, roller bearings and gear teeth. These phenomena have not yet been clarified. The aim of this study is to reveal the mechanism of corrugations on the surfaces in rolling contact. In the first report, the corrugations caused by plastic deformation are developed by experiment with no slip between two wheels. The corrugation profile and wheel oscillations are measured in real-time, and characteristics of transient phenomena on the corrugation formation are analyzed in detail it was found that the wavelength of corrugation nearly agrees with that of the vertical natural oscillations of the wheel, but is slightly larger.
