Abstract:
The ident ification principle o f simp le harmon ic exc itat ionm ethod is illustrated. Based on the fact tha t frame structures can be simp lified to series mult-i degree-o-f freedom systems, the stiffness ident-i f ication formu la w as derived through fourier ana lysis o f the structure v ibration equat ion. N um erical simulations w ere carried to validate identificat ion formula using simu lated no ise-free data and simu lated no isy data. The results show that the method can identify the stiffness parameters of frame structure accurately and has a good fault to lerance. Themethod has certa in applicat ion value in structure dynam ic test.
