The Application of Three Order Cumulants Coupling Features in Fault Diagnosis
《International Journal of Modern Nonlinear Theory and Application》2020年第4期81-89,共9页Wenbing Wu Rihua Liu 
Although mechanical vibration is extremely complicated, each fault signal produced by it has its own inherent features, The distinction may be most prominent between the certain components hidden in those features and...
