中文摘要 近年來隨著海上交通安全之重視,航行安全成為了重要之議題,除了船體性能及人員乘坐之舒適性需要達到船東之要求,船舶的耐海性及結構強度也必須加以考慮。兼顧船體性能及航行安全要求之船舶才是符合現代需求之船舶。本研究以二維截片理論為基礎,運用勢流理論並搭配二維源點格林函數以滿足邊界條件,透過設定不同船速、波向角及海況條件可用以探討高速船艇的耐海性能。為驗證本研究方法之可行性,將進一步比較模擬結果與實船量測數據,以確認本研究方法之準確性。在本研究中,將藉由設定不同船體姿態俯仰角,用以探討船體姿態對船舶耐海性之影響,以提供設計人員作為初步設計時之參考依據。
英文摘要 With the emphasis on maritime traffic safety, Safety of navigation has become an important issue. Not only the performance of the ship and the comfortableness of personnel, also seakeeping and structural strength of the ship must also be considered during the design stage to meet the requirements of the ship-owner.
Based on the two-dimensional strip theory, the present study employs the potential flow theory and the two-dimensional source point Green's function to solve the boundary value problems. Seakeeping performance of high-speed boats can be explored by setting different ship speeds, wave angles and sea conditions.
The feasibility of the numerical approach in the study have been verified with sea trial data. Seakeeping performance for high-speed boats have been discussed under various sailing attitude.The comparison results show that the computation result gained very similar trend with the verification object, thus the numerical approach could provide great reference basis during the preliminary design stage.
