NAPA75米内河散货船的总体设计+CAD图纸+答辩PPT

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。而内河散货船主要航行于内陆江河，湖泊甚至是水库区域，用来装载煤炭，矿石，木材等不经包装的货物的船舶，其对于国内运输市场有巨大的竞争优势。

鉴于上述，本文将基于NAPA软件进行75米内河散货船的总体设计。首先，对散货船的研究意义，研究目的及其发展现状进行看了简单概述。之后，根据母型船进行新船主尺度的换算，并校核其排水量，舱容，快速性及其初稳性。然后，利用NAPA软件建立母型船模型，然后根据母型船模型以及新船主尺度进行仿射变换，完成新船模型的构建以及型线的光顺，接着对新船进行分舱以及定义其四大基本载况，并且使用NAPA软件计算该船的静水力性能，以及初步校核该船的稳性。本文附录中还包括了对该船的完整稳性计算，干舷计算和吨位计算。最后完成型线图及总布置图的绘制。该船的设计结果经过各项性能校核，都能满足相关规范的要求。59522

Abstract In recent years, with the continuous development of China's economy, the demand for goods transport is keep growing.The water transport has a lower cost than that of land and air transport, also it has a greater amount of transport which reaches more than ten thousand tons, and thus the water transport has a huge advantages and development prospects relative to other ways.Inland bulk carriers mainly drive in some inland rivers, lakes, and even the reservoir area.This kind of ships transport coals, ores, lumber, and other unpackaged goods,which have a huge competitive advantage in the domestic transport market.

In view of the characteristics above, this paper will be based on the NAPA software for 75 meters inland bulk cargo ship`s overall design .First of all, introduce the significance of bulk carrier,the research purpose and the development status recengty.Second,we make the conversion in new dimensions according to the parent ship, check the drainage volume, tank capacity and speed and stability. After that,we use NAPA software to establish the model of mother ship, complete the conversion according to the parent ship`s model and new ship`s size,finish the new model`s construction and smooth the lines of ship.Next,we need to pide the rooms of ship define four basic loading conditions, and use Napa software to calculate the ship's hydrostatic capabilities as well as the check to the ship's stability.The appendix includes the calculation of the intact stability of the ship, the tonnage calculation and the freeboard calculation. At last,finish the ship line`s drawing and general layout paper`s drawing. The ship`s design results ,which are checked by various performance check, can meet the requirements of the relevant specifications.

Keywords: NAPA、inland bulk carrier；hydrostatic performance；intact stability calculation
