Based the measured flexibility , the identification model of the partial eigenstructure assignment was presented . the linear algorithm , the pseudolinear algorithm and the fully nonlinear algorithm were established , and the comparative studies were carried on the above algorithms . the fully nonlinear algorithm was determined to solve the identification problem based on the measured flexibility 從觀測柔度陣出發(fā),提出了結(jié)構(gòu)識別的部分特征結(jié)構(gòu)分配識別模型,建立了識別問題的線性化、擬線性化和完全非線性算法,并通過對三種算法的對比研究,確定了用于結(jié)構(gòu)損傷識別的完全非線性識別算法。
