Abstract

The Recurrence plot’s recognizing performance was applied in this paper. Signals, recorded at different locations on the structure, are using to reconstruct the phase space of the system’s dynamics and subsequently generate the multivariate recurrence matrix. Multivariate recurrence matrix is then used to construct a novel feature detecting damage combined with singular entropy. It is using for strucure damge identification. Numerical experimentation verified this feature’s validity.
