江苏科技大学本科毕业论文55M集散两用船船体结构规范设计Structure design of 55 M distribution of dual-use vessel hull byrules摘要关键词 :AbstractAlong with the US financial crisis's eruption, the world economics trade situation will have the tremendous change, will then cause the world trade marine transportation quantity growth to slow down, the initiation international shipping market will be turbulent. Therefore, in present, under this business not bright world economics trade situation, the multipurpose ship will be one of ship owners more ideal operation body forms. Because its can adapt many kinds of routes, the high efficiency carries each kind of cargo as far as possible, the use is simple, the construction cost is inexpensive.This paper introduce the basic structure of standardized design process of 55 M distribution of dual-use vessel hull, which is designed, calculated and checked according to CCS Steel Inland river Ships Construction Standard (2009 edition). This ship with raked bow, transom stern of welded steel structure, the material besides the special statement, is the CCSA level steel. second continuous de，cksingle-storey deck houses at bow and stern, using single-propeller aerodynamic balance fulcrum rudder. Cargo cabin district is longitudinal frame, the bow, stern and superstructure is transverse frame.The main contents of this article include:1. Development and forecasting of multipurpose ship; the structural characteristics of container ship; the methods and what should be pay attention to during the design.2. The basic process of 55 M distribution of dual-use vessel hull structure design, and examination of bending intensity of the midship section in district of cargo cabin.3. Mapping of the midship section, basic construction profile and planKeywords : Multipurpose ship; container ship; structure design; map of the midship section; map of basic construction profile and
