基于HHT的齿轮箱复合故障诊断研究

提出一种基于HHT的齿轮箱复合故障诊断方法。该方法将齿轮箱故障振动信号进行Hilbert-Huang变换,得到信号的Hilbert能量谱,通过谱分析实现齿轮箱复合故障的识别。齿轮箱故障实验信号的研究结果表明:该方法能有效诊断齿轮箱的复合故障。

Research on Gearbox Composite Fault Diagnosis Based on Hilbert-Huang Transform

A method to fault diagnosis of gearbox based on Hilbert-Huang transform was presented.Hilbert-Huang transform was used to the fault vibration signals of gearbox to get Hilbert energy spectrum.The composite fault can be identified by analyzing the spectrums.The experimental results show that Hilbert-Huang transform can effectively diagnosis composite fault of gearbox.
