Model Updating of Complex Structures Using the Combination of Component Mode Synthesis and Kriging Predictor

Table 1

Comparison of dynamic properties between condensed and uncondensed FEM.

Mode	Frequency (Hz)		Frequency error (%)	MAC*
	Condensed FE model	Uncondensed FE model
1	6.91	6.88	0.44	0.91
2	7.13	7.12	0.14	0.90
3	11.00	10.96	0.37	0.92
4	16.93	16.91	0.12	0.90
5	17.20	17.19	0.06	0.92
6	20.54	20.60	0.29	0.93

∗MAC represents the modal assurance criterion.
