A vibroacoustic energy density field approach for an automatic sub-structuring method of complex structures in low- and medium-frequency ranges

Abstract : An energy density field approach for the vibroacoustic analysis of complex structures is proposed. This method is developed for an uncertain vibroacoustic computational model. An important result of using this method is the construction of an automatic sub-structuring method for complex structures which is applicable at low- and medium-frequency ranges. Though the proposed energy method is inspired from the Statistical Energy Analysis (SEA) method, it is quite different. Mainly, in the stochastic context in which the method is applied the statistical properties of the FRF were observed even in the low- and medium-frequency ranges which makes the method applicable in these frequency ranges.
