摘要：

轧机工作辊的稳定运行是保持轧制过程稳定，保证轧件质量的重要前提。实践证明，工作辊处振动复杂，并且存在耦合现象。根据实际工况，综合考虑轧辊偏移、液压压下系统、轧制工艺等因素建立了轧机工作辊3种属性的耦合振动模型。利用MATLAB求解了该模型的固有频率及不同轧制工艺参数下系统振动响应情况，得到了不同轧制参数对轧制过程的影响及各属性振动的相互影响关系。通过对某钢厂F2轧机实测信号的分析，验证了结论的正确性。此研究为抑制轧机振动、实现轧制工艺参数最优化提供了依据。

The stable operation of working roller in rolling mill is an important prerequisite to ensure the stability of rolling process and the quality of workpiece. The practice has proved that the vibration of working roller is complex and exists the phenomenon of coupling vibration. According to the actual working conditions, the coupling vibration models of three kinds of different working rollers were established by considering the roller offset, the hydraulic cylinder system and the rolling process. Then, the natural frequencies and the vibration response under different rolling process parameters were solved by MATLAB, and the influences of different rolling parameters on the rolling process and the interaction of each property vibration were obtained. Furthermore, the conclusion was proved by analyzing the measured signal of a F2 rolling mill in a steel mill. Therefore, the study provides a basis for the suppression of the rolling mill vibration and the optimization of rolling process parameters.
