軍事載具在設計上與一般民用之載具不同，其相異之處即軍用載具必須面對戰場的威脅，為確保艦艇上之裝備能持續運作，艦艇在建造時即應對艦艇之抗爆震能力有所規範與要求，尤其船艦重要裝備及基座之抗爆震能力，在裝艦前採用實品測試法加以驗證，以確保A級和B級裝備符合爆震要求。但若艦艇上之裝備、系統、基座等體積過於龐大且重量甚重（如主機、推進軸系、桅杆及武器系統等）無法使用實品測試法或實船測試來驗證其爆震能力者，美國海軍同意此類重要儀裝可採用動態設計分析法－DDAM進行抗爆震評估。由於世界各國對於裝備抗震的探討大多著墨於水面艦艇，對於水下載具上裝備之抗震分析極為少數，因此本論文主要之目的即在建立水下載具上重要裝備在爆震環境下之評估方法。在裝備抗爆震分析之研究，本論文採用動態設計分析法（DDAM），其乃是結合美國海軍實船實驗所歸納整理出之爆震設計譜，配合有限元素軟體ABAQUS，建立爆震反應譜分析法，並以水下載具上之雷達基座系統及柴電動力主機基座系統為研究對象進行抗爆震分析，評估潛艦內部重要儀裝在爆震環境下之受力及反應情形，期能提供水下載具裝備抗震設計之參考。

In combat operations, a warship can be subjected to air blast and underwater shock loading. Therefore, design criteria of a warship are different from civilian ship. To keep shipboard equipment on task, the shock resistant capabilities of warship should be required and specified during building construction stage. Especially, the shipboard equipment and mount defined as Grade A and Grade B equipments should be verified using with experiment method. The Dynamic Design Analysis Method (DDAM) is the U.S. Navy’s specified analytical method of qualifying non-testable equipment and supporting structures to withstand the effects of shock, especially heavy or huge shipboard equipment (such as engine, propulsion shaft, mast and weapon system). Most researches have tended to focus on the shock resistant performance of surface ship. Assessment of shock resistant for submarine has rarely been examined. The aim of this work is to develop an assessment method for submarine equipment under shock environments. In this work, this study adopts DDAM in conjunction with a shock design spectrum inducted by U.S. Navy after performing full-scale trials in establishing a shock response spectrum analysis, to be coordinated by using finite element’s discrete and calculating procedure. Radar mount system and diesel-electric engine mount of submarine was used to take the explosion shock as an example to analyze the shock resistant performance. The response of shipboard equipment under shock environments was calculated. Analysis results provide a valuable reference of shock resistant design for shipboard equipment.
