Abstract: The dynamic properties of rolling mill are significantly influenced by many coupling factors. According to the coupled mechanical and electric dynamics theory, the global coupled equations for the dynamic analysis of planishing mill CM04 of Shanghai Baosteel Group Corporation were derived, by using finite element methods. These elasto-dynamic equations establish the coupling relations among the stand vibration system, torsional vibration system, driving motors, etc. It provides theoretical basis to a certain extent for globally dynamic simulation, analysis of stability of motion, prediction of abnormal operating mode, globally optimum design and control, etc.
Key words: rolling mill; dynamic analysis; electromechanical coupling
