Rolling Bearing Fault Diagnosis Based on GUI System

Abstract Rolling bearing can be used in many complex weapon equipments to reduce friction and improve their productivity. Accordingly, a rolling bearing fault diagnosis and life prediction system interface is made by using the graphical user interface system module of MATLAB so that the theoretical value of the local defect frequency can be calculated based on the possible fault types of the main structure of the rolling bearing. Then the fault category of bearing can be identified by comparing the impact interval frequency of bearing fault extracted by Hilbert transform with the theoretical fault frequency.
