一般注記A study to establish a prediction method for vibro-acoustics of satellites during rocket launch has been conducted using a multidisciplinary analysis method of fluid, acoustic, and vibration. This coupling method consists of following four elements: numerical analyses of (1) sound generation, (2) sound propagation, (3) sound permeation, and (4) vibro-acoustics of payload. In the sound generation analysis, it can be seen from FEM analysis of a simply modeled deflector that a strong resonance occurs at low frequency. From the sound propagation analysis using a hybrid code of an Euler flow solver and a Linearized Euler solver, the characteristic sound wave from the modeled deflector has low frequency. For the sound penetration analysis, a static analysis using a FEM solver is conducted to simulate the deformation of a modeled faring by acoustic pressure. A simply model of a satellite's primary structure with some stiffeners is constructed for solving eigen value problem and for analyzing transient response by the FEM solver. From these analyses, low modes of stiffener vibration are excited.
