Proper orthogonal decomposition (POD) is applied for examining modal activity. The extraction of proper orthogonal modal co-ordinates (POCs) is outlined. The proper orthogonal values (POVs) are the mean squared values of the POCs. The number of POVs above the noise floor provides a bound on the number of significant modes based on POVs above the noise floor. The ideas are illustrated on a linear cantilevered beam experiment. The displacement ensembles are obtained by processing six strain… CONTINUE READING
