Abstract
From a viewpoint of multibody dynamics, we propose modeling and formulation for such a motion of the rolling disks, and discuss about the mechanism of corrugation development based on the result of the numerical simulation. The unilateral contact between two rolling disks is expressed as a constraint condition on contact point and its surface profile changes with time due to wear development. In particular, we focus on the self-excited vibration with time lag for two disks with rolling contact. In this system, a phase difference between the corrugation profile and the contact force fluctuation influences corrugation development.
