The creation of numerical model for a dynamic structure on the base of the finite element method and the method of experimental modal analysis integration is presented. The paper deals with compatibility of model created from measured data and finite element model. The error in measured modes is eliminated on the base of orthogonality condition. Correlation of finite element model is defined in spatial domain. The process of error uses an optimization procedure to the norm. FE model update example of structure illustrates the presented theory.
