摘要
本文讨论了Hilbert变换的基本原理,以及基于Hilbert变换的包络解调方法在机械故障诊断中的应用。实践表明:对于具有调制现象的设备故障诊断,基于Hilbert变换的包络解调方法,具有明显的诊断意义,是一种可靠的诊断方法。
The principle of Hilbert transform, envelope analysis based on Hilbert transformation and its application in machinery fault diagnosis are discussed. The practice shows that the envelope demodulation method based on Hilbert transformation offers a reliable method for machinery fault diagnosis.
