阐述五十多年以来连轧机振动问题提出、研究内容、研究进展和研究展望。通过现场测试发现连轧机存在垂扭耦合振动、液机耦合振动、弯扭耦合振动和机电耦合振动现象；然后通过理论研究、仿真分析也证明了连轧机耦合振动的存在及特征规律；最终确定了连轧机振动性质为机电液界多态耦合振动。据此开发了抑制连轧机耦合振动的通用技术，发明了“连轧机耦合振动解耦抑振器”并在某连轧机组上成功应用，取得了良好的抑振效果。
It focuses on the raising of the rolling mill vibration problem over the past half-century,the research con-tent,the research progress and the research perspectives.The phenomenon of vertical and torsional coupling vibra-tion,hydraulic-mechanical coupling vibration,bending and torsion coupling vibration,and electromechanical cou-pling vibration are found through scene test.Then the existence and characteristics of rolling mill coupling vibration is proved through theoretical study and simulation analysis,and the nature of electrical-mechanical-hydraulic-inter-face coupling vibration is ultimately determined.General inhibition technology of rolling mill coupling vibration is developed,and the ‘tandem mill coupling vibration suppressor’is invented and successfully applied on a tandem mill.And the vibration suppression effect is good.
