摘　　要：针对某钢厂CSP轧机在轧制薄规格产品时时常出现异常振动现象,在MATLAB中建立了F3轧机主传动系统的仿真模型,对轧机在咬钢过程和异常振动过程的动态特性进行了仿真研究,并结合现场实测数据,得出了振源在主传动系统中的科学解释,为最终确定振源提供了依据。In view of the exceptional vibration problem of CSP hot rolling mill while rolling light gauge sheet, simulation model of the F3 mill＇s main drive system was built using Matlab. Then dynamic characteristics of the system during biting and exceptional vibrating were analyzed. Finally, combining with the field testing data, a conclusion that the vibration source exists in the main drive system was scientifically interpreted. This conclusion has provided ideas for finding out the vibration source.
