| Abstract: | The identification of modal parameters by using time series analysis istudied in this paper. The principle of identification of modal parameters byARMA and ARMAV models is introduced, the abilities identifying modalparameters in seperate modes, different SNR, high damping, close modes byusing simulated experiments are checked, the conclusion is that the ARMAVmodel is an efficient method identifying modal parameters. |
