文摘

Theoretical and experimental research on non-Gaussianity and non-stationarity excitation. High-cycle fatigue of flexible structures excited close to natural frequencies. Non-stationarity excitation significantly impacts the fatigue life. Non-stationary vs non-Gaussian excitation were found much more important.
