摘要：
The parameter identification of a rubber conveyor belt model is the key problem in researching the dynamic characteristics of large belt conveyors. The parameter identification equation of the standard solid model for the rubber conveyor belt was derived by employing the viscoelastic dynamics theory and the Fourier series fitting method, and was validated by experiments. The quadratic polynomial fitting was performed on the identification results of experimental data under different load conditions. The influences of the load displacement amplitude and frequency on the constructive model parameters of the conveyor belt were analysed. The results show that with the increase of load amplitude, the viscosity coefficient first decreases and then increases, the elastic modulus E1 increases by a small amplitude, and the elastic modulces E2 increases by a large amplitude quickly. With the increase of load frequency, the viscosity coefficient, the E1 and E2 decrease gradually. The accuracy of the fitting equations was validated by experiments. © 2017, Editorial Office of Journal of Vibration and Shock. All right reserved.
