Abstract:Vibration test and analysis system based on virtual instrument technology was built on the LabVIEW platform, combining hardware the purpose of fault signal real-time acquisition and analysis could be achieved, this system also had the function of off-line data processing. As LabVIEW did not support Hilbert-Huang transform, polymerization empirical mode decomposition and local mean decomposition algorithm, therefore the HHT module, EEMD module and LMD module were implemented through independent development. Finally, using this system to acquire and analyze rolling bearing inner race fault signal,the results show that the test system can meet the application requirements of the actual vibration test.
