摘要货船是指用于载运旅客和货物的船舶，又称商船。用船舶作为运输工具的优点是运载量大，营运成本低。在国内，货物运输的40％都由货船完成，货船运输团队是在能源运输、国际贸易是一支主力军，在国民经济发展中起着举足轻重的作用。随着我国经济的发展，沿海、沿江以及内河等区域对货物运输的要求越来越高，造成航运市场运力吃紧，使得运力紧张满足不了运量快速增长需求。因此，设计一艘小型货船以船小、航距短、速度快的特点合理选择主尺度以谋求一定的经济性。本船采用的主尺度选择范围方法是母型船方法。这种方法是根据同类型吨位相似的实船的主尺度资料，结合新船的具体要求，分析母型船在载重能力、积载因数、航速、稳性等主要性能和使用要求等方面与新船的差异，根据确定主尺度的基本原理进行分析，确定新船主尺度的主要范围。本次总体设计一公分为四个阶段，分别包括确定船舶主要要素阶段，绘制型线图和总布置图阶段，船舶主要性能计算阶段，以及螺旋桨设计阶段。船舶总体设计，融合了船舶各方面的知识，极大的促进了设计者对所学知识的掌握与运用能力。本次设计还运用maxsurf软件对其进行三维建模，优化船体及确保计算结果的精度。61819

Abstract The cargo ship is used for vessels carrying passengers and goods, also known as also known as merchant ships. The advantages of using the ship as transport is carrying capacity, low operating costs. In China, 40% of the goods are completed by the cargo ship, cargo transport is the main force of energy transport, international trade, plays an important role in the development of the national economy. Along with the development of our country's economy, the demand for goods transportation is more and more high along the coast, along the river and inland river, shipping market capacity so tight, so tight capacity can not meet the rapid growth in traffic demand. Therefore, the design of a small cargo ship with small, short flight away, fast speed to seek a reasonable choice of the main dimensions of a certain economy. The ship selection method of main scale is generating type ship reconstruction.This method is according to the tonnage of the same type similar to the real ship principal dimensions data, combined with the specific requirements of the new ship. Analysis of the mother ship type in load capacity, stowage factor, speed, stability, main performance and use requirements and new ship differences, according to determine the basic principle of the main scale analysis to determine the main scope of the new owners scale.The overall design is pided into four stages, including the main elements of the ship to determine the stage of general arrangement and type of line drawing stage, the main computing of ship performance and propeller design. The overall design of the ship integrate the knowledge in all aspects of the ship, greatly contributed to the designer to master the knowledge and skills.
