This paper presents a new error localization technique which uses measured FRF and analytical dynamic stiffness data. The technique is based on the computation of the so-called Miscorrelation Index (MCI) for each coordinate as a function of frequency, which has non-zero numerical values through the frequency range of collected data for coordinates carrying error. Also, a model updating routine based on the minimization of this index is introduced. This routine does not require analytical FRF data for the complete model. However, the incomplete experimental data are extracted using modal expansion, which requires modal analysis of the analytical model. The updated models are used in the modal expansion process. The application of the method is illustrated through examples on a discrete system and a beam model by using computationally generated test data.
