潛艦自主逃生球艙上浮過程運動計算模擬

Motion Simulations of Ascent Process for an Independent Escape Sphe-re of Submarines

潛艦的研發設計和整個服役過程中，逃生和救援一直是一個備受討論和高度重視的課題。集體自主逃生球艙作為一種具有高度主動性的逃生裝置，可以保護人員的安全，及時有效地提高失事潛艦人員的自救能力。本研究的主要目標是利用計算流體動力學(computational fluid dynamics，CFD)方法，模擬潛艦逃生球艙的上浮運動過程，從而建立這種設計的分析評估工具。本研究使用求解RANS方程的CFD計算軟體Ansys Fluent，並充分利用其提供的6DOF模組和動態網格技術，模擬逃生球艙的上浮軌跡。本研究的逃生球艙參考了德國IKL/HDW的設計，透過建立一系列設計參數模型，包括重心高度、初始速度、材料設計變更和海流速度，比較計算逃生球艙運動特性的差異，找出影響逃生球艙整體性能的關鍵因素，為設計最佳逃生球艙提供參考。

Safety and rescue have always been highly discussed and prioritized aspects throughout the development and service of submarines. The Group Independent Escape Sphere serves as a highly proactive escape device that protects the safety of personnel and enhances their ability to self-rescue in the event of submarine accidents. The main objective of this study is to utilize Computational Fluid Dynamics (CFD) methods to simulate the ascent motion process of the submarine's escape sphere, thereby establishing an analysis and evaluation tool for this type of de-sign. This study utilizes Ansys Fluent, a CFD software that solves the Reynolds-Averaged Navier-Stokes (RANS) equations. It fully uses its provided 6DOF solver and dynamic mesh technology to simulate the ascent trajectory of the escape sphere. The design of the escape sphere in this study is based on the IKL/HDW design from Germany, and a series of design parameter models are estab-lished, including the center of gravity height, initial velocity, material design variations, and ocean current velocity. By comparing the differences in the calculated motion characteristics of the escape sphere, the key factors affecting the overall performance of the escape sphere are identified, providing references for designing the optimal escape sphere.
