ABSTRACT

Finite element analysis (FEA) technology has been widely used in the tire industry, but how to obtain a reliable tire model easily and accurately still deserves to be studied. In this paper, we mainly study the influence of different constraints of the tire cross-section on the FEA of tire. Taking the 205/55R16 semi-steel radial tire as an example, the tire cross section under the free state and the constrained state with the rim plate was surveyed, and the finite element model was established. In the establishment of the finite element model, the Neo-Hooke constitutive model was chosen to describe the rubber material and the Rebar model was selected to describe the rubber-cord material. Finite element analysis of the contact patch, radial stiffness and inflated outer contour of the tire is carried out to compare with the actual tire test results. Hence, we can find a more reasonable modeling method. The results show that for the inflatable outer contour, the cross-section in the constrained state of the rim meets the modeling requirements better. For the contact patch and radial stiffness, the cross-section under the free state is more suitable for the modeling requirements.
