摘要我国具有较长的内河航道和庞大的货运需求量，其内河航道的货运密度高于世界的大部分国家。为了满足这样的货运要求和复杂多变的航道环境，需要设计不同类型的船舶以满足航运需求。同时，在考虑经济性的情况下，小型内河船同样发挥了重要的作用，小型内河船具有装载灵活多变的优点，而且，大部分航道仅能通航100吨级以下小船。因此，为满足航运需求，设计这样的小型内河船符合市场需求。本次设计采用母型船改造法，通过母型船数据确定设计船的主尺度，型线设计优化，总布置设计，性能计算以及螺旋桨设计。总体设计是一项全局性的设计，是船舶总的概要设计，设计中既要结合母型船的数据，也要综合考虑本船的性能特点、使用航道、经济性要求等，因此设计中要综合考虑。本船运用CAD软件进行型线设计和总布置设计，利用maxsurf进行了性能计算，使船体精度得到有效保证。95192

Abstract China has a long inland waterway and a huge cargo demand, the inland waterway freight density is higher than most of the world's countries。 In order to meet such freight requirements and complex and varied waterway environments, different types of vessels need to be designed to meet shipping needs。 At the same time, in the case of economic considerations, small－scale riverboat also played an important role, small－scale riverboat has the advantages of flexible and flexible, and most of the channel can only navigable 100 tons below the boat。 Therefore, to meet the shipping needs, the design of such a small river boat in line with market demand。 This design uses the master ship transformation method, through the master ship data to determine the design of the ship's main scale, profile design optimization, the total layout design, performance calculation and propeller design。 The overall design is a global design, is the ship's overall summary design, the design is necessary to combine the data of the parent ship, but also a comprehensive consideration of the performance characteristics of the ship, the use of waterways, economic requirements, so the design to be integrated consider。 The ship uses CAD software for line design and total layout design, the use of maxsurf performance calculation, the hull accuracy is effectively guaranteed。
