1、l5050 米水泥运输船的结构设计米水泥运输船的结构设计（浙江海洋学院 船舶与建筑工程学院，舟山 316000）摘摘 要要本次毕业设计是对 50m 水泥运输船的结构设计，主要分为以下几个方面来进行设计：一、通过母型船的资料和新船的任务书来确定设计新船的型线图。因为新船任务书要求的主尺度除了船长和型深，其他都相同，而且两者的差距很小。又因为本船基本没有平行中体，所以通过型线比例的变换来改变型值是可行的，然后利用新的型值表来绘制新的型线图，并进行了光顺与协调。二、利用新的型线图和母型船的一些资料来做结构计算。结构计算主要是利用规范的计算选取外板、甲板、型材、上层建筑以及其他构件的规格。由于本船船长
2、小于 65 米，不用进行总纵强度的计算，只需取材的剖面模数大于规范要求的最小剖面模数即可，当然为了满足强度，取材时尽量保守。三、通过型线图和结构计算书以及母型资料来绘制基本结构图、典型横剖面图和横舱壁图。以横舱壁图为例，利用型线图在量取该肋位上的高度和半宽值来确定该横舱壁的外轮廓，再利用结构计算关于舱壁的板厚和型材规格来绘制骨架，绘制过程中参考母型船资料。其他图也基本类似，不一一列举。四、总结设计过程中的一些经验和遇到的困难，以及解决这些问题的方法，为后续结构设计的提供经验。本次设计的新船满足任务书的要求，结构强度的校核也满足文献1的要求。【关键词关键词】 水泥运输船；结构设计；规范设计；尺寸
3、确定structure designing of 50 meters cement carrierlhuang jianschool of civil engineering architecture and civil engineering，Zhejiang ocean university，zhoushan，zhejiang 316000 Abstract The graduation design is a structure design of 50m cement carrier, which is mainly divided into the following several
4、 aspects in design:First, confirm to design the lines plan of the new ship according to the parent ships data and new ships TOR. Because the new ships TOR requires the rest of the principal dimensions are the same, except the length and depth, which are also required to have a small gap between thes
5、e two. And because this ship nearly has no parallel middle body, it is feasible to change lines offsets through copy type transformation, and then draw lines plan using new offsets table.Second, use new lines plan and some information of parent ship to do structural calculation. Structural calculati
6、on mainly takes advantages of standard calculation to select shell plating, deck, bar, superstructure and other construction elements specification. Since the length of this ship is less than 65 meters, longitudinal strengths calculation is not necessary, just make sure that the section modulus for
7、drawing materials is larger than the smallest section modulus. Of course, in order to satisfy the intensity, when you are drawing materials, it should be as large as possible.Third, design basic construction plan, model body plan and transverse bulkhead plan, by using lines plan, structure calculati
8、ons and some parent ship data. Now, take drawing transverse bulkhead plan as an example, it uses lines plan on the height and width of lifting this Rib bit to ensure the periphery of transverse bulkhead. Then it uses structural calculation about thickness of plating of bulkhead and bar standard to d
9、raw skeleton, with the reference of parent ship during this time. Other plans are similar and they will not be list here one by one.Fourth, summarize some experience and difficulties met during the design process, and methods to solve these problems, in order to rise experience in structural design.
10、 The design of a new ship meet commitments requirements, and profiles checking intensity and also satisfy the document 1 requirements.【Keywords】cement carrier; Structure design; Standard design; Size determine目目 录录l摘 要 I绪 论11 总体部分21.1 设计要求和母型资料21.1.1 设计任务书21.1.2 母型船舱室分布情况31.1.3 母型船主尺度41.2 型线生成42 结构部分52.1 结构规范设计计算52.1.1 外板52.1.2 甲板102.1.3 单层底122.1.4 舷侧骨架142.1.5 甲板骨架192.1.6 船端加强242.1.7 水密舱壁252.1.8 主机基座312.1.9 上层建筑312.2 主要构件汇总512.3 基本结构图552.4 典型横剖面图552.5 横舱壁图
