Mechanical Fault Diagnosis based on LCD Information Entropy Feature and SVM

Mechanical Fault Diagnosis based on LCD Information Entropy Feature and SVM

A new approach for mechanical fault diagnosis based on local characteristic- scale decomposition（ LCD） information entropy feature and support vector machine（ SVM） is proposed. Firstly,the fault mechanical vibration signal is decomposed by using the LCD to obtain a certain number of intrinsic scale...
