Combining the GHM model of ZN-1 viscoelastic material with the finite element method commonly used in engineering, the dissipation degree of freedom is introduced to transform the nonlinear differential equation due to ZN-1 viscoelastic material into a general second-order stationary linearity System model. The GHM model is compared with the most commonly used standard linear model and fractional derivative model. The results show that the method proposed in this study to determine the GHM model parameters is correct
