The results of the experiment show that the peak value, rms, standard deviation, crest factor, kurtosis value and impulse value of the vibration signals can distinguish between the normal and abnormal conditions of the ball bearing when the level of noise is low
常用包絡解調技術對此類信號進行分析,但易受噪聲影響,使得齒輪或滾動軸承的故障特徵難以凸顯。本文從研究相關函數的特性入手,經理論證明,發現自相關函數並不改變調制信號的調制特徵,但具有顯著的降噪特點。
