Abstract

A multistage technique is presented for the determination of the modal characteristics of a vibrating structure. This method relies on the evaluation of the parameters of eXogeneous Autoregressive Moving Average (ARMAX) models that achieve a maximum of the likelihood function corresponding to a measured structural response. The estimation of a long ARX model is first accomplished. Then, an iterative technique is presented for the determination of the ARMAX parameters from their ARX counterparts. The selection of the model orders is discussed and two examples of application are presented that demonstrate the usefulness of the method for both simulated and experimental data.
