摘要
在轴承滚子裂纹缺陷无损检测中,对滚子采用敲击激振方法,分析敲击所发出的声音的频谱谱形特征,揭示因裂纹使滚子受激所发出的声音的音频特征的变化规律。
Hammering-excitation was adopted in the nondestructive testing of bearing rollers＇ gaps to analyze the hammering audio frequency spectrum characteristics so as to reveal the changing regularity of the audio frequency characteristics excited by bearing rollers＇ gaps.
