基于HHT变换的电动机故障信号频率分析
|
摘要
提出将HHT变换(Hilbert-HuangTransform,HHT)中边际谱理论应用于电动机故障信号的HHT分解和频率跟踪研究的新方法,并通过实例验证Hilbert-Huang变换在电动机故障信号频率分析中的应用。
A new method of motor fault signal decomposing and frequency pursuitting based on marginal spectrum of Hilbert-Huang transform (HHT) is presented. The advantage of Hilbert-Huang transform method method was validated to pursuit frequencies of actual motor fault signal.
