| Resumo: | This Master’s Thesis delves into the exploration of wear phenomena in tires, aiming to define its essence and behavior in vehicle dynamics. The endeavor extends to classifying the type of wear mechanisms including frictional, hysteresis, adhesion, and abrasive wear, through their historical context and their relevance on tires. Experimental testing and theoretical modeling, such as TM Simple and TM Easy, along with a nonlinear single-track model, are used to simulate and analyze tire forces and how they change with increasing wear. The data obtained was then used to predict and analyze vehicle behavior under specific conditions. The results reveal that worn tires exhibit higher peak forces at lower slip angles, indicating a quicker response but lower stability, generally. Front tire wear affects vehicle instability significantly more than rear tire wear. This research underscores the importance of accurate modeling and integration of dynamic factors to improve the understanding and prediction of vehicle behavior with worn tires. Future work will focus on incorporating dynamic load transfer and the use of advanced tire models to improve simulation accuracy |
