A Signal Processing Method for Extracting Shaft Speed Information from Vibration Signal

EasyChair Preprint 7045

Abstract

In the case of no shaft speed measurement, the effective acquisition of shaft speed information is the premise of speed-related fault feature extraction, so it is necessary to preprocess the vibration signal and extract the shaft speed information from the vibration signal. In this paper, a signal preprocessing method for extracting shaft velocity information from vibration signals is described in detail. Based on the theory of signal processing, this paper summarizes the method of extracting shaft velocity signal without shaft speed measurement, and verifies the effectiveness of relevant theoretical methods and shaft speed extraction accuracy based on practical application cases.
