摘　　要：针对钢企冷轧厂精密轧辊磨床存在的一种振动故障,分析了磨削工艺参数对振动的影响,并通过振动位移和加速度信号的检测和FFT频谱分析,得到了振动信号的谱特征。通过故障分级排除方法结合谱特征分析,找出了产生这种振动故障的原因,提出了消除这类故障的方法,并为防止这种故障的再次发生提出了相应的解决办法。A type of detecting method for vibration default of precision roller grinder of cold rolling factory was introduced. Ac-cording to influence of grinding technical parameters on vibration,and assisting by detecting and FFT analysis of displacement signals and acceleration signals,frequency character of default vibration was gotten. By default classification elimination method combining frequency analysis,default reasons were found,and a correct method for default elimination and avoidance was given in end.
