In order to meet the needs of fault diagnosis on machines, we designed the vibration signal processing system. Using the graphical development tool of LabVIEW, we realize the process of vibration analysis and basic signal analysis methods. The system is able to preprocess the original vibration signal and extract the features on time, frequency and time frequency domains. We used simulation signals and open vibration databases to do tests of functions of the system. Choosing a set of datas based on the Case Western Reserve University Bearing Data Center Website as an example, the results tells that the vibration signal processing system we designed can identify the frequency of fault with a relative error of 0.84%, and has the advantages of flexible parameter setting, visually displayed results and strong extendibility, providing the basic platform for the vibration testing which is used to realize fault diagnosis on machines.
