Friction-induced self-organization of a one-dimensional array of particles
Résumé
We study the frictional motion of a linear array of parallel identical cylinders on a plane where all interparticle and particle-plane contacts can be described by a Coulomb friction law. The entire system can be characterized in its steady state by an effective coefficient of friction and an effective inertia, both varying with the external driving force. In the steady-state regime, the organization of the array appears as regions involving different rotation modes (sliding with no rotation, rolling on the support, alternate rotations, etc.). The mechanisms leading to this self-organization in modes are studied analytically.
