In this paper, the growth mechanism of corrugations on rolling surfaces caused by plastic deformation has been examined by experiments. Using an experimental machine with the rolling contact of two wheels, whether the corrugations grow or diminish has been determined by changing the natural frequencies of many-degrees-of-freedom vibration systems. In the case of a system with two degrees of freedom, rigid support of the roller rig leads to long-wave corrugation due to the first coupled natural frequency. On the contrary, soft support introduces short-wave corrugation. Namely, the wave length and stability conditions of corrugations depend on the coupled natural frequencies. These conditions of corrugation stability gained by experiments agree with the theoretical calculations using models of a non linear self-excited system.
