因應國艦國造政策,我國海軍刻正執行多樣新式艦艇設計建造,其中成果包含近期完工之新型兩棲船塢運輸艦,由於其船型特殊,國內對其船型之研究資料相當稀少,且國外相關資料亦屬機密等級,皆不易取得。故參考現有資料,研究兩棲船塢運輸艦(母船)於靜止狀態、登陸小艇(子船)入塢過程及航行狀態之波浪效應與運動響應,對各項條件與船體外型作最有效評估,進而提供我國海軍未來後續艦之設計精進。
本研究主要分為三大部分,第一部分係藉由基於二維截片理論與源點分佈法之模擬程式,模擬母船於不同狀態下之響應振幅運算子(Response Amplitude Operator, RAO)。第二部分係藉本系拖航水槽執行多種條件船模試驗,透過慣性量測器與波高計量測,求解母船與子船各條件下之運動狀況。第三部分則比對模擬與試驗數據,驗證模擬程式與船模試驗之可靠性,同時亦辨識兩者數據間之差異性,以供未來精進時,可能遭遇之窒礙問題。
由本研究結果可以得知,子船運動反應與母船槽內波浪狀況具一致性,即海象越高,槽內波浪越大,子船運動亦越大。並證實母船在頂浪狀況時,母船與子船運動反應將是最佳表現,對於我國海軍相關艦型操航人員而言,具實際參考價值。

In accordance with the national shipbuilding policy, the Republic of China Navy has been carrying out the design and constructing various new vessels. Among them, the new amphibious transport dock was recently completed. Due to its unique model, there is very little information about it in Taiwan. Moreover, the relevant information from abroad is also confidential and not easy to obtain. Therefore, we studied the wave effect and motion response of amphibious transport dock (mother ship) in stationary state, landing dinghy (child ship) in docking process and sailing state by referring to the available data. Then, the various conditions and hull shapes were evaluated most effectively to improve the design capability of our Navy's future follow-on vessels.
This study was divided into three parts. In the first part, we simulated the response amplitude operator (RAO) of the mother ship under different conditions by using a simulation program based on two-dimensional strip theory and source distribution method. The second part involved the execution of a multi-conditions tank experiment by a NCKU towing tank. By using the inertia measuring device and wave height meter, the motion conditions of the mother ship and the child ship under different conditions were calculated. The third part compared the simulation and test data to verify the reliability of the simulation program and tank experiment. The discrepancies between the two data were also identified for future refinements that may be encountered.
The results reveal that the test results of the wave condition in the tank with the test results of the hull motion of the child ship, the responses of the phenomenon are generally the same. That is, the bigger the sea state, the bigger the wave in the tank, and the bigger the motion of child ship. The motion of mother ship and child ship is optimum at head sea condition. Overall, the present results can be as the practical reference for the Navy user.
