| Abstract: | A lumped mass model with two degrees of freedom for the vertical vibration system of four roller hot strip rolling mill stand is proposed, and then the parameters of dynamic model, include the equivalent mass, equivalent stiffness and its natural frequencies, are calculated by Matlab package. The correctness of the model is verified via field vibration testing and signal analysis in the strip rolling process. |
