• Abstract:Due to the complex constitutive relationship of tread rubber and the strong non-linearity of the dynamic contact relationship between tread rubber and road surface, the torsional deformation characteristics and distribution mechanism are difficult to be modeled theoretically in the tire contact patch. In order to accurately express the nonlinear flexible large deformation of tire tread block under torsional condition, the constitutive theory modeling of tread rubber based on continuum mechanics and the constitutive model verification based on improved digital image correlation are studied. A novel constitutive model considering the hyperelastic, viscoelastic and frictional property of tread rubber is established. A full-field measuring equipment for torsional deformation of tread block is established based on machine vision technology. The digital image sequence of instantaneous torsion deformation is analyzed by the improved digital image correlation to obtain the strain rate distribution characteristics and distribution law of the marker points and the whole area of the tread block. The analysis results demonstrate that the proposed constitutive model is feasible to predict the full-field distribution characteristics and distribution trend of tread rubber blocks in the contact patch.
