Gearbox Fault Diagnosis Based Wavelet Analysis
-
摘要: 對測取的齒輪箱振動信號進行了離散小波變換,提取了齒輪箱螺栓拉斷的故障信息.結果表明,小波變換或小波分析為判斷、預防同類事故提供了一種有效的分析手段.Abstract: Vibration signals of a gearbox were analyzed by discrete wavelet transform. The abruption information of a bolt in the gearbox was obtained. It is shown that wavelet analysis provides an effective analysis technique for judging and avoiding the same accidents.
