A non-linear viscoelastic constitutive model composed of Mooney-Rivlin model and multiple Maxwell models is used to calculate the high frequency dynamic characteristics of rubber mounts. The equivalent mechanical model of the rubber vibration mount is established and the difference between the drive-point dynamic stiffness and the cross-point dynamic stiffness is analyzed. The analysis shows that the use of the cross-point dynamic characteristic test method can eliminate the influence of the additional inertial force in the test, which is suitable for rubber mounts’ high-frequency dynamic characteristics test; at the same time, a finite element model of the rubber mount is built to analyze its cross- point dynamic stiffness and drive-point dynamic stiffness. The analysis results are compared with the experimental results which verifies the finite element model and the correctness of the mechanical model. This article gives the identification method and results of hyperelastic parameters and viscoelastic parameters in the constitutive model in the frequency domain of rubber materials. Using the identified hyperelastic and viscoelastic constitutive model parameters, the dynamic characteristics of a certain rubber mount are simulated, then compared with the experimental results under different loads, it got a good simulation effect. Finally, a method for optimizing the high-frequency dynamic stiffness of the rubber mount is given and it is used and achieved good results in the actual experiment.
