MODAL ANALYSIS OF RECTANGULAR WOOD PLATES WITH DIFFERENTS BOUNDARY CONDITIONS
Journal Title: Natural Resources and Sustainable Development - Year 2011, Vol 1, Issue 1
Abstract
In modal analysis, mechanical systems with a few inputs and hundreds of outputs have to be identified. This requires adapted frequency-domain estimators designed to handle large amount of data in a reasonable amount of time. Today, modal analysis has become a widespread means of finding the modes of vibration of a machine or structure. Modes are inherent properties of a structure, and are determined by the material properties (mass, damping, and stiffness), and boundary conditions of the structure. Each mode is defined by a natural (modal or resonant) frequency, modal damping, and a mode shape (“modal parameters”). If either the material properties or the boundary conditions of a structure change, its modes will change.
