Acoustic-Based Rolling Bearing Fault Diagnosis Using a Co-Prime Circular Microphone Array

This study proposes a high-efficiency method using a co-prime circular microphone array (CPCMA) for the bearing fault diagnosis, and discusses the acoustic characteristics of three fault-type signals at different rotation speeds. Due to the close positions of various bearing components, radiation so...
