Abstract: The environmental test spectra for a rigid model missile are established by tailoring field test data The time-frequency analysis of vibration acceleration stress associated with flying boundary conditions is made based on wavelet decomposition A corrected method to determine environmental test time is proposed The results show that the test time obtained by way of time-frequency technology is greatly less than the standard value
