Використання моделі авторегресії та інверсійного фільтру для вібродіагностування електричних двигунів електровозів

Abstract

The application of AR filter technique for diagnosis of rolling bearing is based on autocorrelation measurements and is thus insensitive to phase relationships which can be used to differentiate noise from impulses. The MED technique can make a use of the phase information by means of the higher-order statistical characteristics of the signal, in particular the kurtosis, to enhance the ability to detect bearing faults.
