Abstract:
      The finite element analysis method was used to predict the compression deformation of cylindrical rubber component，and compared with the experimental data to judge the calculation accuracy of different constitutive equations.The results showed that for the stress-strain test，when only the uniaxial tensile（UT） test datas was used to fit the constitutive equation，the merits of the constitutive equation could not be judged solely by the fitting precision.The overall precisions of calculating results was greatly improved when UT，planar tensile（PT） and equibiaxial tensile（ET） test datas were used to fit the constitutive equation，and the merits of the superelastic constitutive equation could be judged according to the fitting precision．For the superelastic constitutive equation，the high fitting precision equations of O_Ni，P_Ni，VdW，Marlow，etc. could be used if the UT，PT and ET test datas were provided；while RP_Ni，AB and Marlow equations could be used if only UT data was provided.
