Structural Damage Identification of Modal Parameter Multi-sample Based on Improved SABO
ZHOU Xutao
Abstract：A structural damage identification method is proposed based on an improved subtraction-average-based optimizer,and it is applied to damage identification of modal parameter multi-sample under the influence of noise and incomplete modal infor-mation.The cantilever beam structure is taken as the research object.Considering the effects of noise and incomplete modal informa-tion,the accuracy and stability of damage identification are studied,and the performance of the improved algorithm is analyzed.The results show that the proposed structural damage identification method has a damage identification accuracy of over 91.6%and has the advantage of stable damage identification performance.
