主　　题：Rolling mill vibration Coupling dynamic model Automatic gauge control Mill modulus control gain Vibration suppression 

摘      要：The rolling mill vibration is characterized by the coupling effects among mechanical,electrical,hydraulic and interfacial *** influence of the mill modulus control gain in automatic gauge control on the vibration in hot rolling mills was ***,an experiment related to the mill modulus control gain was carried out in the hot rolling mill process,and it was found that the rolling mill vibration increases with the mill modulus control ***,based on the Sims rolling force method,the coupling dynamic model was established to explain this ***,the influence of mill modulus control gain on the vibration was analyzed numerically on the basis of the coupling dynamic ***,the agreement between the experimental results and the simulation results was confirmed and the measure reducing the mill modulus control gain was obtained to relieve mill vibration.
