A Simple Method of Computing Signal Order Tracking Fast in Time Domain

Order tracking spectrum analysis is an effective method used in the research of transient vibration signal. Through careful study of its principles and applications in vibration test, a new simple formula of calculating the signal order tracking fast was brought forward. With the means mentioned above, a coarse order tracking of vibration signal could be derived easily in time domain. In the mean time, some principles of how to select the parameters in order tracking spectrum analysis were discussed with the help of the new method. Finally, the experiments showed its feasibility and validity in application of real-time processing and analysis of vibration signals.
