| 摘 要近些年，随着我国经济的持续发展，对于货物运输的需求量越来越大。而水上运输相对于陆地运输和航空运输，其成本更低，且运输量更大，往往达到万吨以上，因而水上运输具有一定的优势和发展前景。而散货船作为代表船型，有着不断增长的市场需求。鉴于上述，本文为5000 吨近海散货船的结构设计，在计算中使用 CCS《国内航行海船建造规》（2015）。计算中应该按照规范要求进行计算船中货舱区总纵强度校核，使用规范设计法进行计算。本船是典型的双层底单舷侧货船船型。本文的主要内容包括：1.散货船现状，散货船的结构特点，规范设计原则。2.船体结构规范设计计算，及船总纵强度的校核。3.根据计算出的结构尺寸，在Auto CAD 中画出中横剖面图、基本结构图。并根据规范对不足的地方进行补偿，有加强的地方重新计算。58710 毕业论文关键词： 散货船；结构；强度；规范 Abstract In recent years, with the continuous development of China's economy, the demand forgoods transportation is increasing. Compared with the land transport and air transport,water transport has lower cost and greater transport capacity, which is often more than tenthousand tons, so it has certain advantages and development prospects. As a representativeof the bulk carrier ship, there is a growing market demand.This topic for the structure design of 5000 tons of bulk carriers in offshore, in the calculation using CCS "domestic sailing ships building regulations" (2015). The calculation should be in accordance with the specifications for the calculation of longitudinal strength middle ship area calculation, calculated using standard design method. This ship is a typicaldouble bottom single side cargo ship.The main contents of this paper include:1, bulk carrier status, bulk carrier structural characteristics, the standard design principles.2, ship structure design calculation, and the total longitudinal strength of the check.3, According to the calculated size of the structure, in the Auto CAD drawing in thetransverse section of the map, the basic structure.And in accordance with the norms of theplace to compensate for deficiencies, there is a strengthening of local re calculation.
