“…Through the longitudinal slip test, the relationship between the slip rate and the longitudinal force of the tire under different speeds and load conditions was obtained. Then, the data are fitted by the PAC2002 model-related formulas such as formula (5)(6)(7)(8). The slip rate-longitudinal force curve relationship shown in Figure 9 is obtained.…”

Select 215/55 R17 radial tires for material test to obtain relevant material parameters. Use these parameters to build a finite element model and conduct longitudinal slip simulation. The relationship between longitudinal force and slip rate at different speeds and loads was determined by tire longitudinal slip tests. Then the longitudinal slip simulation results are compared with the test results to verify the feasibility of the model. The circumferential and axial Rebarforce of the belt layer at different speeds and the extreme value of the circumferential Rebarforce on the reverse-envelope of different skeleton materials are analyzed. The results show that: in the static state, the cord force of the belt layer will show a trend consistent with the direction of the cord arrangement. As the speed increases, the belt cord force exhibits significant fluctuations and asymmetry. The Rebarforce of the turn-up points on the belt and ply is significantly smaller compared to the fetal crown ply. The Rebarforce at the fetal crown and belt wrapping points at 60km/h is smaller than at 40km/h and 80km/h. The cord force of the fetal crown ply and the belt ply is much more affected by the load than that of the ply.

“…32 Garcia and Zhou respectively developed a real-time tire physics model to estimate tire longitudinal force using tire strain. 33,34 Tire rubber materials were mostly filled with carbon black particles, which were aimed at improving the mechanical characteristics of the tread rubber material, 35 and the types of carbon black were increasingly diversifying, mainly including: short carbon fiber, 36 silicon carbon black, 37 and clay carbon black. 38 The tread rubber composition structure was shown in Figure 1.…”

The rolling and sliding state of the tread rubber material within contact patch was very important to the handling stability and safety of the vehicle. In this paper, first, the absolute coordinate system was introduced into the digital image correlation method, which improved the ability of the traditional digital image correlation method to solve the large deformation of polymer material surface. Second, a new calculation method of rolling friction coefficient based on the brush model was proposed. Third, a non‐contact full‐field rolling dynamics experimental device was developed to study the effects of carbon black components, rotational speed and vertical load on the rolling mechanical characteristics of tread rubber material. On this basis, the rolling mechanical characteristics of tread rubber material with different formulations were obtained by analyzing the distribution properties of global strain rate, full‐field longitudinal speed and full‐field longitudinal acceleration and the variation laws of transverse/longitudinal strain rate, trajectory of marked points, stress‐strain hysteresis curve and rolling friction coefficient. Finally, the influence mechanism of carbon black composition on rolling mechanical properties of tread rubber material was revealed.
