Relations between contact model quantities and tyre/road noise

Résumé

This paper deals with the relation between contact parameters obtained from real road surface textures and rolling noise levels measured using a close-proximity method (CPX). The road surface is partitioned into a set of rough asperities and the tyre tread is modelled by an elastic half-space. A partition algorithm which identifies road asperities is first applied to three dimensional surface textures measured on several real road surfaces. Then contact parameters describing the load-penetration relation on each asperity are estimated using a matrix inversion numerical method. These parameters are used to solve the contact problem which gives an estimation of the dynamical contact forces at the tyre/road interface during rolling. The contact quantities are compared for different road surfaces and correlated to the CPX noise levels.
