子午线轮胎带束层部位的有限元分析

Using the finite element analysis software ABAQUS,taken the material non-linearity,contact non-linearity and tire structure non-linearity into account,a three-dimensional nonlinear finite element model for 195/65R15 semi-steel radial tire was constructed.On this basis,the force deformation of tire and tire belt were investigated and the force and deformation of cord in different belt parts was analyzed in air inflation and static load conditions. The results show that the cord in belt axially forced distribution and the tire grounding zone stress distribution is similar,it is central axis symmetrical distribution,its maximum value appeared in the end is about 10N;And it can be obtained that cord end the maximum circumferential deformation is about 16mm, neutral ground maximum axial deformation is about 4mm from circumferential and the axial deformation of cord in different belt parts.?
