規則波中船舶之參數橫搖運動

On Parametric Rolling of Ships in Regular Seas

摘要


本文主要為初步探討船舶於規則波浪中的參數橫搖(Parametric rolling)現象。針對此種特殊的船舶運動現象進行全面性的認識,包括了解發生的整個歷程、分析發生的機制、現象背後的原理,並試圖從此環境下的船舶運動方程式之數學理論分析,來佐證解釋參數橫搖的現象。並將研究所得結論,應用於評估新船設計是否會發生參數橫搖,以及選擇避免發生參數橫搖的船舶航行操作措施之實例,說明此研究的實用性。

The main objective of this paper is to study on the parametric rolling of ships in regular seas. A comprehensive perception work was proceeded for such special phenomenon of ship motion. The overall process of the parametric rolling of ships was studied. The mechanism and principles of such motion were analyzed detailedly. The phenomenon of parametric rolling has been explained by way of the mathematical analysis of the ship motion equation. Whether the parametric rolling for a ship in seas occurs or not, and the guidance for ship operation to avoid such motions were practically demonstrated using the results of the study.
