Fault Diagnosis of Rotating Machinery Based on Multisensor Information Fusion Using SVM and Time-Domain Features

Autor: Ling-li Jiang, Hua-kui Yin, Xue-jun Li, Si-wen Tang

Publikováno v: Shock and Vibration, Vol 2014 (2014)

Multisensor information fusion, when applied to fault diagnosis, the time-space scope, and the quantity of information are expanded compared to what could be acquired by a single sensor, so the diagnostic object can be described more comprehensively.
