摘要
提出了基于Hilbert-Huang变换和时频域参数指标相结合的机车轴承故障诊断方法,分别对时频域参数指标诊断方法、Hilbert-Huang变换诊断方法进行了理论分析和研究,通过试验验证了此方法能有效提取机车轴承的故障特征频率。
The fault diagnostic methods of locomotive bearings are put forward based on parameters of time - frequency domain and Hilbert - Huang transform, the fault diagnosis theory and methods are analyzed respectively. The experiment show that the fault characteristic frequencies of locomotive bearings are picked up effectively by the method.
