MULTI-DIMENSION LAPLACE WAVELET AND THE APPLICATIONS IN FLIGHT FLUTTER TEST

摘要

From the view of mode parameter identification, Laplace wavelet and correlation filter are introduced in this these. An improved method called Multi-dimension Laplace wavelet is presented. The construction and implement of the wavelet are studied. Numerical simulation and true flight flutter test data are used to analyse the features of the method. The result show that the new wavelet technique are reasonable and feasible with the great application potential in the data processing after flight flutter test.
