中文摘要 | 本文乃在探討一具中央縱向水密隔艙壁之十五萬噸中型雙層船殼油輪在結構佈置 及結構強度上之問題。即對此雙層船殼油輪最重要的結構佈置設計:船側翼壓載水艙寬度、 雙重底壓載水艙高度、雙重底間縱桁分佈及雙層殼間縱桁分佈等,建立一系列之變化有限元 素模型,以有限元素法進行解析計算,藉此分析比較得知這些結構佈置參數對雙層船殼油輪 之結構強度有何影響。希望在一系列之計算比較下,能提供船廠對雙層船殼油輪的雙重殼間 寬度,雙重底間高度及層間加勁材配置等參數有更深入之瞭解,期能提高所建造之雙重殼油 輪的效益。分析結果顯示:雙重底高度是所有改變參數中,影響結構強度最大的要素,尤其 是對位於雙重底附近之構件。雙重底高度愈大,能很有效地降低其應力。而雙層殼間寬度增 大,亦能大幅減少雙層殼附近構材的應力。此外,增加雙重底間縱桁及雙層殼間之縱桁配置 ,對船底及船側亦能達到減少相對變位之效。 |
英文摘要 | This study will analyze the structural arrangement and safety of a middle-size, 150 k DWT, double hull tanker in which there is a center line longitudinal corrugated watertight bulkhead. FEM analysis is carried out to a series of models which have different depths of double bottom and widths of double sided shell, as well as different numbers of bottom girders and side stringers. The results are as follows; The depth of double bottom is the most important bactor of all on the design viewpoint to a double hull tanker. Deeper the double bottom, less the stress which the structure in the bottom of the ship has. When the widths of double sided shell become larger, the structure near shell gets less stress. Besides, the arrangement and the numbers of bottom girders and side stringers are influential in reducing the relative deformation of double bottom and side shell, respectively. |
