Research Of Vibration Analysis And Measurement System For Rotating Machinery Based On Virtual Instrument Technology

In this paper, with the study of rotating machinery vibration analysis and measurement method, a kind of rotating machinery vibration analysis and measurement system is designed, which is based on virtual instrument technology. The system is designed on LabVIEW workbench and has a lot of functions, such as signal generation, data acquisition, time domain analysis, frequency analysis, rigid rotor balance, fault diagnose and so on. It is convenient to measure and analysis in work site with the usb_daq equipment and notebook. Compared with the traditional instrument, it has a lot of advantages, such as friendly interface, easy operation and high-powered and it has high apply value in rotating machinery test and measurement. In the research of FD(fault diagnose), I have put forward a method based on linear-categorizes theory and proved this method is correct by lab test.
