A systematic method is presented for developing Test-Analysis Models (TAM) which can be used with modal survey test data to update and correct analytical loads analysis models. The method utilizes superelement capability developed for component mode synthesis to generate and correlate the TAM representation at the component level before proceeding immediately with the much larger and more expensive system level TAM analysis. This approach greatly reduces the time and effort required while maximizing the understanding of the analytical model system dynamics. The method is applied to develop a TAM representation for an analytical model of the NASA/General Dynamics Shuttle Centaur.
