Static finite element modeling of radial tires

Pneumatic tire is one of the rather complex motor vehicle components. Stress-strain relationship of rubber is highly nonlinear and rubber is nearly incompressible. The reinforcement in form of textile or steel cords which have very high elastic muduli compared to rubber and the microbuckling of the cords in rubber matrix makes the analysis difficult. Frictional contact with ground and rim, asymmetric loading, and large displacements and strains under normal service conditions are further sources of complication. With the development of digital computers and finite element codes, it is now possible to model the tires more precisely. Static finite element tire models having different levels of complexity are presented in this study. In all models, the reinforcing textile and/or steel plies and microbuckling, frictional contact, and large displacements are included. In some of the models, nonlinear stress-strain relationship of rubber is also included. Results obtained from the models are validated by experiments and compared with the available results in literature.
