| 摘 要： | 全世界薄板坯连铸连轧机在轧制薄规格带钢时都出现不同程度的严重振动现象,导致带钢和轧辊生成明显振痕,从而影响企业的产品质量、外部形象和经济效益。利用自制综合遥测系统对轧机振动参数、力能参数、电参数和工艺参数等进行全面的现场综合测试,经过对测试信号的时域分析和频域分析获得振动的特征及规律;通过理论研究和仿真研究,发现轧机确实存在扭垂耦合振动、机电耦合振动和液机耦合振动现象,确定轧机振动的性质为机电液多态耦合振动。据此对电气传动控制系统和AGC系统进行参数修改和优化,将设计的二阶扭振抑制器应用在主传动控制系统中和对AGC参数进行优化,辊系振动明显降低,有效地抑制了轧机机电液耦合振动现象,取得了显著的经济效益和社会效益。
