It not only in relation to the major benefits of the country, including defense of peace territorial sovereignty and sovereign rights over the territorial waters, flight rights and the administration of the frontier regions, and so on, also is the direct expression of the national image is one of the exercise of national sovereignty identity. The Sino Russian border in the middle reaches of Heilongjiang and is an important channel of Heixiazi Island waters. Russia on Heixiazi Island after the demarcation, Heixiazi Island waterway sovereignty governance receiving task subsequently, the regional water and land boundaries from the new transfers, also on the waters of channel measurement, navigation mark protection proposed new responsibilities and new request, this thesis research ship equal to on Heixiazi Island waterway comprehensive measurement and navigation mark protection, co-ordination of Heilongjiang, Wusuli River Channel rapid measuring, surveying and mapping analysis, AIDS to navigation protection tasks. Based on the Sino Russian border 200 ton ship navigation measurement task as the background, the study of its influence on the construction of the lower longitudinal strength of ships. First of all domestic and foreign research background to explain the lower building research inland ship superstructure mainly influence on longitudinal strength of ships; the superstructure of the longitudinal strength of the actual strength of the ship and the actual application; finite element software MSC.Patran to stop the whole ship infinite element modeling, hydrodynamic calculation software under different working conditions, the dynamic pressure loading on the whole ship model; MSC.Nastran on the ship to stop the infinite element direct calculation, the condition is no differences and there is a lower layer building built with standard calculation results of mold force request to carry on the comparison, obtained the whole ship strength can satisfy the standard request, also verified the board to take Aluminum Alloy material as reasonable to build; at the same time, two cases of calculation results were analyzed, the construction of the longitudinal deformation of the whole ship and turns against the initial effect; further study under the Layer built effect on the main hull, for different types of superstructure longitudinal tortuous intervention level stopped by analysis, summed up the different types of superstructure effects on the longitudinal strength of ships. 目录: 摘要 5-6 ABSTRACT 6-7 目录 8-10 第1章 绪论 10-16 1.1 探讨背景 10-12 1.1.1 航道背景 10-11 1.1.2 航标测量工作船 11-12 1.2 论文探讨的目的和意义 12-13 1.3 国内外上层建筑对总纵强度作用探讨回顾 13-15 1.4 本论文探讨主要内容 15-16 第2章 船舶上层建筑强度与总纵强度理论 16-23 2.1 上层建筑强度理论 16-20 2.2 总纵强度理论 20-22 2.3 本章小结 22-23 第3章 船舶模型建立 23-32 3.1 船体结构 23-27 3.1.1 航标测量工作船结构形式 23-27 3.1.2 航标测量工作船主尺度及主要参数 27 3.2 有限元模型的建立 27-29 3.3 模型信息 29-30 3.3.1 坐标系 29 3.3.2 单位制定义 29 3.3.3 模型规模 29 3.3.4 材料参数 29-30 3.4 有限元模型 30 3.5 本章小结 30-32 第4章 计算工况及载荷 32-37 4.1 边界条件 32 4.2 计算工况的选取 32-33 4.2.1 装载工况的选取 32 4.2.2 确定波浪载荷工况 32-33 4.2.3 确定计算工况 33 4.3 计算载荷 33-36 4.3.1 空船重量与货物压力 34-35 4.3.2 静水压力 35 4.3.3 波浪压力 35-36 4.4 本章小结 36-37 第5章 上层建筑对总纵强度作用略论 37-72 5.1 许用应力 37-38 5.2 有无上层建筑计算结果及略论 38-63 5.2.1 主船体板单元应力计算结果 38-44 5.2.2 主船体梁单元应力计算结果 44-46 5.2.3 上层建筑应力计算结果 46-49 5.2.4 应力计算结果略论 49-61 5.2.5 位移计算结果与略论 61-63 5.3 上层建筑参与总纵弯曲程度略论 63-71 5.3.1 不同长度上建参与总纵弯曲程度略论 63-68 5.3.2 不同高度上建参与总纵弯曲程度略论 68-69 5.3.3 不同材料上建参与总纵弯曲程度略论 69-71 5.4 本章小结 71-72 结论 72-73 参考文献 73-77 攻读学位期间的论文和取得的科研成果 77-78 致谢 78 |
