摘要

本研究依循本實驗室過往發展之模組化建模方式建構潛艦操縱運動模組化數學模式，亦即數學模式將由包含帆罩、艦體、艏翼、艉翼、舵、螺槳、前後水櫃等個別元件的基本性能以及其位置影響效應所構成。運動方程式中的各項流體動力係數以CFD工具ANSYS-FLUENT進行計算。操縱運動模擬係以逐時求解整體六自由度非線性數學模式的方式進行。
　　本研究依據去年蒐集到的潛艦資料建構供試仿擬潛艦構型，並在過往已發展的模組化潛艦數學模式之基礎上，擴充納入水櫃操作模式以建立可模擬潛艦在水下進行下潛與上浮運動之完整潛艦數學模式，並以供試仿擬潛艦構型為例進行水動力係數計算及操縱運動模擬。直線航行、下潛上浮、水平面迴旋運動及拉回測試(Pull-Out Test)等模擬計算結果與資料比對，顯示本研究所擴充開發完成的數學模式與模擬系統軟體可合理的模擬潛艦在水下的六自由度操縱運動，此計算模擬工具應足以提供操船模擬之用。

The purpose of the study is to develop a submarine maneuvering motion simulation tool. In this study, the modular modeling methodology which has been developed before at my Lab is applied and extended to include the ballast and trimming tanks for descent and ascent maneuvers. Namely, the hydrodynamic forces model of fuselage, sail, bow planes, stern planes, rudder, propeller, ballast and trimming tanks are treated as an individual component, and their interactions are described by another terms with clear physical meaning.
　　Based on the collectable data of a submarine, a simulated submarine configuration is generated for testing the mathematical model and simulation tool developed in the present study. The hydrodynamic coefficients of the simulated submarine configuration are calculated by CFD software of ANSYS-FLUENT.
　　Submarine maneuvering motion simulations are carried out by solving a coupled nonlinear 6-D equations of motions time step by step. It is confirmed that all the simulations of steady forward propulsion, descent and ascent maneuvers, steady turning on horizontal plan, pull-out test for checking the directional stability show reasonable results. We finally concluded that the mathematical model and simulation program system developed in the present study can be expected to be an effective tool for simulating an underwater platform of submarine in the training of anti-submarine operations.
