Abstract:

Measurements and predictions of low-order resonant frequencies and mode shapes have been made for three rectangular aluminum plates, each having a different fillet radius at the attached end. Measurements were conducted using a dual-beam laser vibrometer, and predictions were made using the MSCNASTRAN finite element code. The effects of the fillet radius on the resonant frequencies have been quantified, and a comparison between measured and predicted values is presented. Effects of water loading are also presented. Results show that 1 resonant frequencies increase as the filet radius increases, 2 the predicted resonant frequencies compare favorably with those measured, and 3 water loading reduces the resonant frequencies determined in air. Keywords Plates Resonance Mode shape Laser vibrometer NASTRAN Water loading Dynamic responses Physical properties Structural properties.
