摘要
本文建立了滚动轴承故障信号模型,针对轴承故障诊断中两种不同的诊断方法对故障信号模型分别进行了运算,并在理论上对两种诊断方法的信嗓比大小进行了比较.通过对现场轴承监测诊断对上述比较结果进行了验证.
This paper builds up the fault signal model of antifriction bearings and,based on two different diagnostic methods,respectively calculates the signal-noise ratio of this model.The results are compared theoretically and verified by spot monitoring and diagnosing.
