Abstract: FE model of H445×16521 aircraft tire was established with ABAQUS nonlinear FEA software based on rebar element, and rim fitting, tire inflation and static load application were simulated. Deformation and distribution of the 2D inflated model, width and radius of the inflation section were studied. Stress and strain changes over time of each cords and rubber were analyzed. The results showed that this method was reliable for radial tire modeling.
Key words: ABAQUS FEA; aircraft tire; rebar element; stiffener model
