摘要

This study presents a comprehensive analysis of the overview of tire-road surface interaction by using the latest research tools to ensure a scientific and innovative approach in both objectives and methodology. A spatial model based on the 175/65R14 tire of a Toyota Vios passenger car was developed to build a spatial model to analyze the forces acting on the tire contact surface with the road surface. By referring to published results from the leading tire manufacturer Michelin on the empirical equation to determine rolling resistance, the study extends the calculation of specific parameters by applying the Magic Formula model of Pacejka to analyze the relationship between normal force and slippage affecting the tire-road adhesion to the road surface at the contact area. Using Matlab software, we investigated the factors of contact pressure distribution was elliptical with the highest pressure at the center being close to 2.0 bar and gradually decreasing towards the edge. The dynamic normal force varied from −5.2 kN to +14.8 kN around the equilibrium value of 4.9 kN when the vehicle moving over sinusoidal road surface. The results reveal the tire's interaction surface with the road surface during vehicle movement. These results can provide a scientific basis for optimizing tire design, improving fuel efficiency, and enhancing vehicle safety.
