英文摘要：

The research mainly focuses on the development process, realization methodology of the hard-ware and software functional models and the actual application of the fault monitoring and diagnostic system based on LabVIEW. In allusion to the mechanism and features of the mechanical vibration signal, in the analyzing model of signal offer time domain dimensionless parameter analysis, frequency analysis, cepstrum Analysis and envelope analysis etc. Through these methods can judge the running states of the equipment, identify the features of the faults.
