This paper application the ABAQUS engineering analysis software finite element analysis of radial tire . Create a finite element model of the radial tire , the rubber matrix material is incompressible Yeoh material model , carcass and the belt layer materials using Rebar film unit ; same time , considering the geometric nonlinearity, material nonlinearity and tires of the tire structure contact nonlinear . Finite element model , this paper established first analyzes the the inflatable conditions tire deformation , stress , strain distribution ; followed by the rubber matrix material belt layer shear stress , shear strain analysis and the belt layer of stress Rebar unit strain analysis, and were given a corresponding relationship curve . Finally , the static contact conditions tire with the ground contact patch shape and subsidence of the tire contact patch . In this paper, the the free inflatable conditions tire deformation , stress , strain analysis basically consistent with the actual situation ; static contact condition tire contact patch shape analysis conclusions with the literature data are in good agreement , established in this paper is limited element model is reasonable , can provide some theoretical guidance for the optimal design of the structure of radial tires .
