中文摘要 | 本文以開口薄壁樑扭轉理論分析船深H,船寬B,舷板厚t ,船底板厚t 以及封 閉巢室幾何形狀參數之變動對駁船型船扭轉強度之影響。首先,以導函數方式就單殼駁船 型船推導橫剖面之剪力中心,翹曲常數,扭轉常數,扭角以及趐曲應力與船深,船寬,舷 板厚以及船底板厚等參數之敏感度。接著,以複巢開口薄壁樑扭轉理論所建立Warshp程式 ,就雙殼駁船型船分析封閉巢室深與巢室寬變動對扭轉強度之影響。 |
英文摘要 | In this paper, the influences of sensitivity analyses on the torsional strength of the pontoon ship with a large deck opening due to variation of the principal dimensions of the cross section and the geometric parameters of the closed cellar are examined by using the torsion thin-walled beam theory. Firstly, the gradient information in the sensitivity analysis of shear center, warping constant, torsion constant, torsion angle and warping stress for single- hull pontoon ships is derived by the direct differentiation method. The sensitivity calculation is performed numberically with respect to the cross sectional parameters such as depth of cross section, breadth of cross section, breadth of cross section, breadth of cross section, thickness of the side plating t and thickness of the bottom plating t Finally, the influences on the torsional strength of a double-hull pontoon ship with respect to the geometric parameters of the closed cellar are also studied by using the Warshp program based on the multi-cellar mixed torsion thin-walled theory. |
