Abstract: The advantages and disadvantages of some main excitation methods for the flutter experiments are briefly described in the paper.Then the ground-model experiments were conducted by using impulse excitation,finite-bandwidth white noise excitation and harmonic excitation,and the structural response was measured at the same time.On the base of STD,ARMA and LSCE,the frequency and damping ratio were identified.Through comparing and analyzing them and the results from NASTRAN,the influence of model exciting techniques and parameters identification methods were discussed.Finally,the optimal scheme of model excitation and parameter identification was evaluated for flutter test techniques.
