| 摘要 沿海散货船是连通近海地区运输的重要船型，它具有方便、快捷的特点，是航运行业的主力船型。本文在设计任务书的要求下对 5500 吨沿海散货船的总体设计进行了研究，参照已提供的母型船，结合公式计算船舶载重量，确定主尺度范围，排水量校核，舱容校核，重量重心的估算，稳性估算，航速估算，主尺度的确定，得到和设计任务书相符合的结果。对照母型船绘制船体的总布置草图，采用自行设计法设计型线，完成型线图的绘制。按照《国内航行海船法定检验技术规则》（2012）的规定进行干舷校核还有吨位的计算。结合寻找散货船设计过程中自己存在技术问题，从一些错误里研究存在的内容偏差，最后尝试提出自己对总体设计中存在不足的理解，通过这次设计使自己对知识的运用更加熟练，积累船舶总体设计中所需要的经验，表述自己对以后的船舶总体设计未来进一步发展的一些看法。本文主要研究内容： ① 散货船的现状与发展趋势 ② 5500T沿海散货船总体设计计算书 ③ 船体总布置图和型线图的绘制58674 毕业论文关键词：船舶总体设计，主尺度，干舷校核，吨位计算，型线图 Abstract Coastal bulk carrier ship communication is an important offshore areas of transport, It has a convenient, fast characteristics, the shipping industry's main ship. Under the guidance of the design task book of 5500 tons bulk carrier Coastal overall design of the research, To provide the parent ship, for example, combined deadweight ship formula, to determine the main scales, displacement check, check tank capacity, estimated the weight of the center of gravity, stability estimation, speed estimate, determine the main scales to give results and consistent design task book. Control parent ship general arrangement drawing sketches of the hull, used to design method design profile, draw complete profile graph. There were freeboard checking tonnage calculated in accordance with the provisions of “domestic voyage ship Rules of statutory inspection techniques" (2012) Looking combined bulk carrier design process, the presence of its own technical problems, study existing content deviation from some errors, the last attempt to make their own shortcomings understanding of the overall design, the design by making use of their own knowledge of more skilled, accumulation ship overall design experience required, to articulate their ship after the overall design of the future to further develop some of the views. The main research: ① Bulk carrier status and development trend ② 5500T coastal bulk cargo ship general design calculations ③ General arrangement drawing of the hull and the type of chart Keywords: general design、main dimensions、freeboard correction、Ship tonnage calculation、lines drawing 目录 第一章绪论-1 1.1研究背景1 1.2散货船的研究现状和发展趋势1 1.2.1散货船的发展状况1 1.2.2散货船的发展趋势2 1.3沿海散货船特点-2 1.4研究方法2 1.5研究目标和内容-3 第二章主尺度的确定4 2.1技术要求和母型船资料4 2.1.1设计技术参数4 2.1.2母型船资料-4 2.2计算载重量-5 2.1.1计算载重量-5 2.3初步选择设计船的主要要素7 2.3.1主尺度选择-7 2.4排水量校核-10 2.4.1估算空船重量10 2.5舱容校核11 2.6估算航速14 2.7重量重心估算14 2.8稳性估算16 2.9主尺度总结-17 2.10本章小结-17 第三章型线设计18 3.1型线设计方法-18 3.1.1型线设计的目的-18 3.1.2自行设绘法设计型线-18 (责任编辑：qin) |
