For the non stationary random response analysis of structures with uncertain structural parameters, the applicability of the conventional perturbation scheme has long been questionable because of the existence of the secular terms.

The cross correlation functions between responses of linear structures undergoing non stationary random excitation consist of two parts: ①a sum of decaying sinusoids of the same form as the impulse response of the original system, ②the other form containing no modal function.

In the combined model the periodio vibration quantity within low frequence range, randomness and nonstationarity of the data are considered, and nonstationary factor and AR time seriers model are applied.

Based on Andrew,we put forward a nonstationary robust and general long memory testing approach.

For the nonstationarity and spectrum chaos of the bearing vibration signal,threshold de-noising based on wavelet decomposition was put forward.

Base on that,the application of wavelet transformation in fault diagnosis to analyse nonstationarity of roller bearing vibration signals with Daubieches wavelet is introduced.
