The work presents experimental results of analysis of an aircraft wing and fuel tank assemblage, using a multivariate ARMA identification technique. A numerical model of the same is obtained and comparison between the model and test results are presented and discussed.11171120Kurka, P.R.G., Araújo, C.A., Automatic process for the determination of modal supersets of residual flexibilities used in the modal synthesis method (1999) RBCM - Journal of the Braz.
