摘要: The verification of a space launcher at the design level is complex issue because (i) lack detailed modeling capability acoustic pressure produced by rocket; and (ii) difficulties in applying deterministic methods to large-scale metallic structures. In this paper, an innovative integrated process described, based on bridging between new semiempirical jet noise model hybrid finite-element method/statistical energy analysis (FEM/SEA) approach for calculating acceleration payload equipment within structure, vibrating under external forcing field. result method allowing accurate prediction vibroacoustics interior, using limited computational resources without resorting fluid dynamics (CFD) data. Some examples concerning Vega-C are shown.
