This paper focuses on the modeling and analysis of a four-groove passenger car tire, size 235/55R19, using finite element analysis. The Mooney–Rivlin material model is employed to define the hyperelastic behavior of the tire rubber compounds for all solid elements. The tire rim is modeled as a rigid body using aluminum alloy material, and the beads are modeled as beam elements using steel material. The tire model is validated in both static and dynamic domains through several simulations and is compared to published measured data. The tire is validated using footprint and vertical stiffness tests in the static domain. In the static footprint test, a steady-state vertical load is applied, and the tire–road contact area is computed. In the vertical stiffness test, a ramp vertical load is applied, and the tire’s vertical displacement is measured to calculate the tire’s vertical stiffness. In the dynamic domain, the tire is validated using drum-cleat and cornering tests. In the drum-cleat test, a drum with a 2.5 m diameter and a cleat with a 15 mm radius is used to excite the tire structure and obtain the frequency of the vertical and longitudinal first modes of vibration, that is, by applying the fast Fourier transformation (FFT) of the vertical and longitudinal reaction forces at the tire center. In addition to this test, the tire model is pre-steered on a flat surface with a two-degree slip angle and subjected to a steady state linear speed of 10 km/h to predict the cornering force and compute the cornering stiffness. In addition, the effect of tire longitudinal speed on the rolling resistance coefficient is then predicted at zero slip angle using the ISO 28580 rolling resistance test. The findings of this research work provide insights into passenger car tire–road interaction analysis and will be further used to perform tire rubber compound material model sensitivity analysis.

“…Regarding FEM tire with visco-hyperelastic rubber compound behavior, Srirangam [10] developed the so-called sequentially coupled thermo-mechanical model for tire-road interaction simulation, in which Prony series approach was employed to account for rubber viscosity. Lu, Yang, Wu, et al [11] designed a simplified model with a visco-hyperelastic rubber material response to simulate static and rolling car tires. The accuracy of this approach was estimated at 80 percent after being validated using experimental tests.…”

Considering the present-day environmental and energy objectives set forth by governments and aiming at minimizing carbon footprints and fuel consumption in the transportation sector, it is of utmost importance for manufacturers to enhance tire design. This is because doing so has the potential to revolutionize the automotive industry by promoting advancements in structural performance and fuel efficiency while reducing environmental impact and ensuring safer, more dependable vehicle structural performance. Moreover, such an approach has the advantage that the choice of model’s features such as the geometry and material mechanical properties, is done in a more detailed manner. The mechanical behavior of rubber compounds used in tire manufacturing has a direct impact on the static as well as the dynamic response of tires in various operating scenarios, such as steady state and transient dynamic. However, in the literature, there is a plethora of works that often consider basic rubber constitutive laws without a consistent study of the impact on the model results. Therefore, this paper proposes a comparative study of the static response of a radial tire using finite element method for different choices of incompressible rubber material behavior ranging from elastic(EL), hyperelastic(HE), visco-hyperelastic(VH) to hyper-pseudoelastic(HM). Simulations of an inflated tire and vertically loaded were conducted in ABAQUS Explicit, and the resulting radial deformation, maximum Von Mixes stress, CPU time, contact patch, and contact pressure were selected as four consistent comparisons. The results show that among the four material cases, the VH and HM material models lead to the most accurate result with a shorter CPU time with the latter. Also, their contact pressure and body stress are higher than those of the elastic and hyperelastic models, and this brings an important solution to the disparity between the calculated and experimentally measured contact pressure in previous works.
