摘要
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 modified method to determine environmental test time is proposed. The results show that the test time obtained by time-frequency technology is much less than the standard value.
