Abstract

In this paper the performance of several modal parameter estimation techniques is compared by considering simple mechanical structures as benchmarks. Specifically, among Input/Output techniques, a frequency domain poly-reference method is considered. Among Output/Only techniques, Frequency Domain Decomposition and poly-reference least square complex frequency-domain techniques are used. In order to characterise the performance of the examined methods, one of the important features of the benchmark structures is whether they present close and/or multiple modes
