At last, this dissertation validates that the high-frequency resonance technique based on energy operator optimizing arithmetic is availability with rolling element bearing fault diagnosis. Characteristic parameters, such as crest factor, impulse factor and kurtosis, are sensitive to estimate abnormal noise.
最后,通过实验验证了基于优化能量算子法的共振解调技术在滚动轴承故障诊断中是非常有效的,而峰值因子、脉冲因子和峭度等特征参数均在不同程度上对异音敏感,可以用来初步评价滚动轴承的异音水平。
