The three-dimensional nonlinear bump model is established by using  ABAQUS  software. The anisotropic hyperelastic model established by the strain energy density function , which is used to simulate the property of cord - rubber composites in the flexible bump. The main direction of the material can simulate the geometrical and material nonlinearity of the cord - rubber composite. By modeling the bump structure as a whole, the model is simplified and the calculation efficiency and calculation accuracy are improved. The deformation height and inner stress of the bump structure under different inflation pressures are obtained by three-dimensional nonlinear analysis, the large deformation of cord - rubber composite is also taken into account in the analysis.
