摘　　要：以四辊板带冷轧机垂直振动为研究对象,对轧制过程中轧机辊系的振动情况进行了研究.在轧机垂直振动理论和动态响应理论的基础上,运用有限元分析软件ANSYS建立了轧机轧制过程动力学仿真模型,并对四辊冷轧机的工作辊、支承辊进行了动力学模态分析.研究了轧机工作辊、支承辊固有振型及其在垂直方向上的形变对轧制过程中辊缝变形的影响,对其中影响辊缝变形较大的轧机辊系特定振动频率下的振型进行了详细分析.仿真结果表明,在某些特定的频率时上下工作辊和支承辊在垂直方向上的振动幅度较大.通过对国内某企业2800四辊可逆式冷轧机进行垂直振动工程测试,验证了四辊冷轧机轧制过程动态仿真结论的正确性.The research object of this paper is the vertical vibration phenomena of four rolls cold roiling mill and the vibration of roll system in roiling process is studied in this paper. On the basis of the vertical vibration theory about rolling mill and the theory of dynamic response, a dynamics simulation model of rolling process is established and a dynamic model analysis for the work rolls and backup rolls of four rollers cold roiling mill is carried out by using the finite element analysis software ANSYS. This paper studied the own inherent vibration model of the work rolls and backup roils and how will their deformation in the vertical direction influence the deformation of roll gap during rolling process. Besides, some models of the roll system in specific vibration frequencies which have a great influence on the roll gap deformation have been studied in detail. The simulation results show that the vibration amplitude in the vertical direction of work rolls and backup rolls would be large at some certain frequencies. By performing vertical vibration tests on the 2800 four-roller reversing cold rolling mill of a domestic enterprise, it verifies that the dynamic simulation conclusions about the four rollers cold rolling mill are correct.
