Abstract:
      The stress relaxation test data of damping rubber materials were normalized，and the corresponding viscoelastic constitutive parameters were obtained by fitting the stress relaxation test data with Prony series model.The Prony series factor representing the viscoelastic characteristics was introduced into the Ogden hyperelastic constitutive equation to obtain the constitutive equation of damping rubber material based on time effect，and then the creep characteristics of uniaxial tension, biaxial tension and plane tension modes were analyzed.Finally，the creep simulation and test verification using hourglass spring were carried out.This creep simulation prediction method could provide a new idea for viscoelastic experiment，creep calculation and engineering application of damping rubber materials.
