摘要：
Considering the influence of roll vibration on the rolling force, a nonlinear seven degrees of freedom vibration model was established for the stand rolls system of a four-roll cold mill. The amplitude-frequency characteristic equation of the nonlinear multiple degrees of freedom model was derived by using the average method, further, the bifurcation behavior of the system was revealed in light of the singularity theory. The influence of various parameters on the amplitude-frequency characteristic, and the bifurcation and chaos characteristics of the system were analysed with practical data. The results provide a theoretical reference for studying the kinematics and inhibiting the occurrence of vibration of four-roll cold tandem mills. © 2015, Chinese Vibration Engineering Society.
