Prediction of Tire-Road Friction from Surface Texture and Tread Rubber Properties

Source

Over the past decade the senior author and his students have been working on a purely theoretical technique for predicting tire-road friction. It is based on a postulated model of the tire friction mechanism and hence relies on road surface texture measurements and on road surface water film thickness plus the laboratory-measured elastic and damping properties of the tire tread rubber. The method has evolved into a more mathematically complex procedure after validation tests on a number of roads. Each additional refinement has made the method more accurate but possibly not, at this stage, as practical as simpler, partly empirical methods that recently have been developed elsewhere. The paper, however, which is presented in simple terms, demonstrates that the moderate use of tread rubber temperature categories will enable the sideways force or locked-wheel friction to be predicted accurately for any speed, wetting condition, or tread rubber properties for bald and patterned tires. In the event of the technique being finally validated, it could be largely automated for simplicity.
