Abstract

Considering the main structure and combined performance of multiple composites for renovation tire, the mechanics model, geometric model and finite element model of renovation tire for 11R22.5 loading vehicle were set up, the simulation analysis and experimental research of its deformation characteristics were conducted by using composite laminated structures and finite element large deformation theory, and the same brand and same model new tire was compared. The deformation theory formula of renovation radial tire was amended based on the loading deformation characteristic rules of renovation tire. Analysis result indicates that when inflation pressure is certain, the radial deformation, lateral deformation, grounding length and contact area of renovation tire increase with load increase, its deformations are almost linear, while its radial stiffness hardly changes. When load is certain, the radial deformation, lateral deformation, grounding length and contact area decrease with inflation pressure increase, while its radial stiffness increases. The elastic modulus of renovation tire's carcass is bigger than the one of new tire's carcass. The greater the modulus difference between the two carcass is, the higher the aging degree of renovation tire's carcass is, the lower its remaining service life is, which benefits for predicting the aging properties of renovation tire's carcass.
