Friction noise of sliding/rolling rough surfaces

Résumé

The friction of two solids with rough surfaces produces a typical sound generally called roughness noise. This study focuses on the numerical simulation of what happens into the contact during the sliding. The mechanical equations of vibrating solids in contact are first set. They are solved by a modal approach. The contact is modeled at the scale of surface asperities which requires a very fine discretization. The results show that this approach is several times faster than the classical finite element method. Furthermore, it reproduces the empirical laws observed experimentally and provides the statistical properties of local events which are not accessible by experiment.
