    A Comparison of PSD Enveloping Methods for Nonstationary Vibration (2015)
    In:  CASI
    Details
    Publication Date: 2019-07-13
    Description: There is a need to derive a power spectral density (PSD) envelope for nonstationary acceleration time histories, including launch vehicle data, so that components can be designed and tested accordingly. This paper presents the results of the three methods for an actual flight accelerometer record. Guidelines are given for the application of each method to nonstationary data. The method can be extended to other scenarios, including transportation vibration.
