Abstract：Parameter identification of the rubber conveyor belt model is the key problem in researching the large belt conveyor dynamic characteristics. Firstly, the parameter identification equation of the standard solid model for the rubber conveyor belt is derived and established by employing the viscoelastic dynamics theory and the Fourier series fitting method, and the identification equation is validated by the experiment. Secondly, the quadratic polynomial fitting is performed for the identification result of the experimental data under the different load conditions, the load displacement amplitude and the influence laws of the frequency to the constructive model parameters of the conveyor belt are obtained. The results show that with the increasement of the load amplitude, the variation law of the viscosity coefficient is that the viscosity coefficient first decreases and then increases, the variation law of the parameter E1 is that E1 increases by a small amplitude, the variation law of E2 is that E2 increases by a large amplitude quickly, with the increasement of the load frequency, the viscosity coefficient, the elastic modulus E1 and E2 decrease gradually. The accuracy of the fitting equations is validated by the experiment.
