Development of diagnosis system for rolling bearings faults based on virtual instrument technology

This paper analyses the principle and characteristic frequency of typical faults of rolling bearings, and diagnosis system for rolling bearings faults has been proposed which combine modem virtual instrument technology and thought of analysing rolling bearings faults through Hilbert transform envelop analysis method. This system is based on VMIDS, which is developed by Test Center of Chongqing University and can successfully extract faults information as well as cut off the cost of system.
