| 2 | A hybrid multiple damages detection method for plate structures显示文摘A hybrid method is proposed value to properly identify(SVD)multiple is applied damages reveal for plate structures in this work.and In the to stage detect of the damage damage(ACO)localization,locations.singular In decomposition damage to on singularities in modal shapes,hence colony the stage of to quantification,damage based the detected for location information ant optimization algorithm between is the introduced natural estimate severity by searching damage evaluation database,natural which reveals the relationship frequencies and the damage severity.The modal shapes and the frequencies required in damage localization and quantification carried are obtained the via the wavelet of finite hybrid element method multiple method.for The numerical simulation with and experimental damages.investigation are out to test performance the to free aluminum plates multiple with And the results indicate that the proposed method is effective identify damages of plate structures reasonable precision. | JIANG YongYing XIANG JiaWei LI Bing CHEN XueFeng LIN LiQu | 2017 | Science China(Technological Sciences)2017，60，5： | 1 |
