基于小波分析的齿轮箱故障诊断

Gearbox Fault Diagnosis Based Wavelet Analysis

摘要

摘要: 对测取的齿轮箱振动信号进行了离散小波变换,提取了齿轮箱螺栓拉断的故障信息.结果表明,小波变换或小波分析为判断、预防同类事故提供了一种有效的分析手段.

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.
