    My apologies if this is not the right forum ,
    We do have several suggestions for detecting if a Vibration signal is stationery or not : 

    Following are the  Methods:

    1. Time-Domain: Rolling statistics (mean, variance).
    2. Frequency-Domain: STFT, Wavelet Transform.
    3. Statistical Tests: ADF, KPSS.
    4. Empirical Methods: EMD for analyzing non-stationary components

    My end goal is generate synthetic data for normal vibration of bearings . Appreciate for any suggestions or directions
