Title: Experimental Estimation Of Mechanical Joint Parameters Using Frequency Response Functions And Modal Parameters
Author: Arruda Jose Roberto F.

Abstract: Large structures often consist of substructures connected through mechanical joints, whose dynamic behavior is generally difficult to characterize. In previous publications, the authors have proposed and verified numerically a method to solve the problem of modeling this kind of structure. It consists of updating a component mode synthesis model by adjusting the stiffness and damping coefficients of the joints based on either experimental modal parameters or on measured Frequency Response Functions. In this paper, the applicability of the proposed method is investigated using an experimental example consisting of two beams connected by elastomeric mounts. The issues of mode synthesis with rigid-body modes, sensitivity computation, and convergence are discussed based on preliminary experimental results.
