Vibro-acoustic Analysis of Simplified Satellite Model by Using the Statistical Energy Analysis

단순화된 위성체의 통계적 에너지 해석법을 이용한 음향-진동 연성 해석

At lift-off, the jet noise of launch vehicle produces a severe acoustic environment and the loads induced by the acoustic pressure may be damaging to paylaod and equipments. Prediction of the acoustic environment is needed to support the design and test-qualification of components. Currently, such a high frequency problem is usually dealt with by using the SEA, of which the assumptions match reasonably well with the vibro-acoustic condition of system. (omitted)
