Experimental Modal Analysis of a Sandwich Construction, Glass Reinforced Plastic Composite Deck Panel

Abstract

This report details the experimental modal analysis of a 20-ft by 6-ft sandwich construction glass reinforced plastic panel. The panel includes four compliant foundations, which are designed to be equipment supports. The analysis reveals that below the fundamental resonance of the foundations, the structure behaves in a similar fashion to a uniform plate. The foundations do not show appreciable vibration. Above the fundamental of the straps, there is significant sympathetic vibration between the deck and foundations.
