An improved approach of updating the initial finite element models in comparison with a modal test is presented. This is accomplished by using the reduced models dynamically equivalent to the initial models. The degrees of freedom (DOF) in the reduced models include the generalized coordinates besides the measurement points for a modal test. Therefore, these reduced models can take into account the inertia force at unmeasured DOF and preserve the dynamic characteristics of the initial analytical models regardless of the measurement points. These reduced models are used for a direct analysis/experiment correlation with modal test data. Numerical simulation results are presented to show the effectiveness of these reduced models in the parametric correction of the analytical finite element models.
