In this paper, the novel method for free response signal of large-scale system is proposed. On the basis of random decrement method on the basic idea, two key parameters are discussed. One is the length of the system's output signal N, the other is the reference value of the amplitude A. in order to obtain more precise free response signal of system, using the result of eigenvalues analysis to modify the primary free response signal. Processing the measured acceleration from real system,...
