Abstract
The requirements of analysis-test correlation and model updating of dynamic structural systems, often called system identification, are strongly related to those of Multidisciplinary Design Optimization (MDO). This paper describes how MDO tools have been used to form an integrated environment for performing these tasks. Specifically, it describes how these tools are used to modify modeling parameters in order to make the response of a finite element model better match test results. The techniques shown allow the simultaneous correlation of dynamic structural responses including natural frequencies, normal mode shapes and frequency response functions (FRF's). This methodology forms the basis for an important emerging technology being termed Model Validation and Verification (V&V).
