Abstract
Tire wear degrades the tire performance and also shorten its life. So it is of great guiding significance and practical value to establish wear predicted model of tire for improving its wear resistance. Firstly, a friction coefficient expression is developed based on the investigation of the tread friction characteristics. Then, a numerical wear model is developed and verified by the LAT 100 laboratory test. Finally, the new analytical wear model is present in terms of friction shear stress and wear rate. Results indicate that the volumetric wear rate, surface temperature, weight loss increases when the velocity increases; the wear becomes intense with the increasement of side-slip angle and there is little wear when the angle is zero, while the surface temperature firstly increases and then decreases when the slip angle increases. Finally, a new wear predicted model is developed based on frictional energy density and wear rate.
