摘　　要：针对CSP轧机在轧制高强薄带钢时出现的强烈振动现象,利用在线监测系统对轧机机电液信号进行跟踪测试,获得了轧机垂扭耦合振动信号特征。在此基础上,探讨传动-压下-带钢耦合激励的轧机振动机制,利用ANSYS有限元方法构建传动-压下-带钢耦合激励谐响应仿真模型,求解在多激励下轧机的谐响应特征,得知F3轧机垂振在42 Hz频率处振动响应最大,与现场测试结果基本吻合。研究结果对提高薄规格带钢轧制生产稳定性具有参考价值,同时指出抑制轧机振动的方向。Aiming at the strong vibration phenomenon of CSP rolling mill when rolling high-strength thin strip steel,the online monitoring system was used to track and test the electromechanical and hydraulic signals of rolling mill,and the characteristics of vibration signal for vertical-torsional coupling were obtained.On this basis,the vibration mechanism of transmission-screwdown-strip coupling was discussed,the harmonic response simulation model of transmission-screwdown-strip coupling was constructed by ANSYS.The harmonic response characteristics of rolling mill under multi-excitation were solved,and the maximum vibration response at 42 Hz for F3 rolling mill was obtained,which was basically consistent with the test result on site.The research results have reference value for improving the rolling stability of thin gauge strip,and point out the direction of restraining rolling mill vibration.
