Theoretical Modeling of Tire Wear
In this study, the effects of different parameters on the wear-rate of tire based on the available theoretical models were investigated. The law of conservation of energy in contact patch was used to find the relation between the fracture energy required for propagation of surface cracks and frictional energy. The theoretical friction model and contact mechanics proposed by Persson was used to obtain the frictional energy. In addition, the fatigue crack growth in rubber-like materials to obtain the crack growth rate based on fracture energy was investigated. Finally, the friction model and fatigue crack growth model were combined to obtain a comprehensive theoretical model for simulation tire wear. To assure the correctness of the results, these results were compared with experimental results obtained from a dynamic friction tester developed for this study.
