Research on the Effect of Early Signal Increasing for Rotating Machinery by MED and MCKD

The key to early fault feature extraction of rotating machinery is to effectively enhance the weak vibration signal of early faults. This article first analyzes the minimum entropy deconvolution and maximum correlation kurtosis deconvolution methods, and gives the calculation process of the two methods. The effectiveness of the methods of minimum entropy deconvolution and maximum correlation kurtosis deconvolution on weak information enhancement is analyzed through simulation signals, and the enhancement effects are analyzed and compared.
