Experimental Research on Friction of Vehicle Tire Rubber

A newly developed tire rubber friction test machine is introduced. Friction test method of tire rubber is provided. Test data of tire rubber friction on concrete and icy road surfaces are obtained and analyzed. The effect of different road surface, ambient temperature, contact pressure, and slip velocity on friction coefficient is apprehended. The dynamic friction is introduced to tire semi-empirical modeling, and the accuracy of the model is improved. A way of forecasting tire property on high-rolling speed using data from low-rolling speed tire test is illustrated.
