The response prediction of aerospace sandwich panels is studied through a numerical simulation based on Statistical Energy Analysis. The influence on the structural response to the launch acoustic environment of the design parameters, such as core type, thickness and number of ribs, is examined. The

โฆ Synopsis
A computational procedure is presented for calculating the response of building components to acoustic loads due to spacecraft launch. The methodology described is in-built as routines into a software module &&ACOUP'' which forms part of the OSTA software package for o!-shore and on-shore structural analysis using "nite elements [1]. The software developed can be used to predict the acoustic response of any structure/structural component. One wall panel and one roof panel in each of the two buildings in launch acoustic environment at SHAR, INDIA and KSC, U.S.A. are analysed and the computed acoustic responses are compared with the responses measured at the respective places during the launches.
