摘　　要：针对某厂2180mm冷连轧机在轧制汽车面板时出现的振纹问题,进行了现场连续综合测试。基于对轧制周期内振动信号的分析、比较,掌握了该轧机的振动特征和振动形态,确定了轧机的起振次序。结合轧机的机械固有特性,找到了导致轧机振动的主要来源,即减速机中齿轮1和齿轮2的啮合冲击,据此提出了振纹的抑制措施。生产实际表明,抑振措施对振动及振纹的消除具有较好效果。To the problem of chatter marks on strip surface rolled by 2180mm tandem cold rolling mill in a plant, continuous tracking measurements were executed. The vibration characteristics of the mill were conclu- ded and the vibration order was confirmed by analyzing and comparing the vibration signal during rolling cycle. Through combining with the mill inherent characters, the main source of mill vibration was found, it is the en- gaging impact of gear 1 and gear 2 in reducer. The restrain countermeasure of the chatter marks is derived and proved to be effective for vibrating and eliminating chatter marks in practice.
