摘      要：In view of the complexity of tire structure and working conditions, tire models are often based on complete and accurate test data. In combined with the theory of tire dynamics, the empirical and semi-empirical tire models are built. In order to accurately measure the tire mechanical properties, it is necessary to strictly control the wear state of the tire tread during the tire test. But there is still a certain amount of wear, which does not guarantee the consistency of the data. In order to study the influence of wear on the mechanical properties of the tire, based on the tire footprint pressure distribution model and brush model theory, combined with the brush model theory and the rubber block shear stiffness deformation theory, the tire cornering stiffness model under different wear conditions is established. The footprint pressure distribution model is built based on the results of footprint test under different wear conditions. And combined the test result with different tread wear conditions and the theory of brush model, the tire brush model considering tread wear conditions is built. Based on the above theoretical model, the UniTire tire cornering slip model considering the tread wear state is established. To verify the accuracy of the model, the UniTire cornering slip model is obtained by using the cornering slip data in three tread wear states, and the tire mechanical properties of the other tread wear conditions are predicted. The error between the simulation results of the model and the experimental results is small, which effectively prove the predictive ability of UniTire cornering slip model considering tread wear. This study will help to improve the UniTire tire model and provide theoretical and technical support for the UniTire indoor and outdoor expansion applications.
