本計劃將使用統計能量法，來預測衛星結構中高頻穩態與暫態的振動行為，先期將以中華一號衛為研究目標並對其模型進行測試，而研究項目包含下列幾項： 1.在音震反應下之衛星傳遞路徑分析。 2.在音震反應下之得傳遞近路敏感度分析。 3.在爆振下之振動反應預測。 4.在爆振下之能量傳遞路徑。 5.在爆振下之敏感度分析。 6.爆振之分析將進行實驗比對。而在同時並評估一套可行的結構參數之實驗估計方法。並進行實際量測。並以此為參數修正統計能量法理論模式。 The objectives of this research project is to use Statistical Energy Analysis (SEA) method for the evaluation of the steady and transient vibration response of satellite structures, and the work needs to be done in this project including:1. Vibration transmission path analysis of satellite structure in high intensity acoustic field.2. Sensitivity analysis of the design change of the critical components on the vibration transmission path3. Transient vibration response prediction under explosive loading4. Transmission path analysis under explosive loading5. Sensitivity analysis under explosive loading6. Refinement of experimental technique for extracting SEA parameters.
