FRICTION AND WEAR IN RUBBERS AND TYRES

A unified approach to the entire subject of friction and wear in rubbers and tyres is presented. Friction is regarded as a fundamental energy dissipative mechanism as A result of which surface degradation and wear occur. At the same time the rolling tyre is considered as a combination of rubber elements undergoing prescribed motions in the contact patch, and this elementary macroscopic modelling of tyre frictional behaviour provides a basic understanding of rubber friction and tyre mechanics simultaneously. An analogy between friction and wear mechanism is developed. Thus the adhesion and hysteresis contributions to friction on rough surfaces produce abrasive and fatigue wear respectively, whereas waves of detachment on smooth surfaces appear to produce wear by rolled fragments. The paper concludes with a description of an elaborate experimental rig designed to test elementary friction blocks of rubber or a complete tyre in various braking modes.(a) (TRRL)
