A Wavelet-Multiple Swarm Genetic Algorithm for Cantilever Structure Damage Identification

Abstract A two-stage wavelet-multiple population genetic algorithm identification method is proposed to solve the problem of difficult damage detection cantilever structures. The strain mode then transformed into a wavelet using Matlab toolbox, structure’s location examined singularity principle, and displacement frequency are used determine degree multiple (MPGA). When no information about structure available, this can damage’s extent. For example, numerical simulations tests on cantilevered beam demonstrate method’s effectiveness.
