基于EMD与SSA的齿轮箱分形诊断研究

Study on Fractal Diagnosis of Gearbox Based on EMD and SSA

提出了一套齿轮箱故障分形诊断方法。首先将EMD与SSA相结合,提取信号(尤其是微弱信号)的特征信息;其次通过多重分形从多重角度对提取到的特征信息进行诊断;最后通过分形理论识别出齿轮的3种状态。

A fractal diagnosis method for the gearbox failure was proposed,which firstly has EMD combined with SSA to exactly extract the signals＇ characteristic information,especially the weak signals,and then it has characteristic information extracted through multi-fractal and from multiple perspectives diagnosed and finally it has fractal theory based to identify gearbox＇s three fault types.
