摘 要

本次毕业设计为光65.5m网罩渔船设计。在设计过程中主要参考1025吨灯光网罩渔船为相近的母型船，同时以《钢质海洋渔船建造规范(2015)》，《渔业船舶法定检验规则（远洋渔船2015）》，《贾复渔船设计》，《船舶设计原理》等文献为参考进行设计。在设计过程中综合考虑了船舶的快速性、操纵性、经济性等性能。

毕业设计内容主要包括以下几个部分:

一． 主尺度确定——根据任务书的要求并参考母型船初步确定主尺度，经过重力与浮力平衡进一步确定主尺度，再对容积、航速及稳性等性能进行校核，最终确定船舶主尺度。

二． 型线设计——采用1－Cp法改造母型船型线，通过绘制辅助水线半宽图来绘制设计船的水线半宽图、横剖面图、侧视图，从而得到设计船的型线图。

三． 总布置设计——按照规范要求并参考母型船进行总布置设计，区划船舶主体和上层建筑，布置船舶舱室和设备。

四． 性能计算——对设计船的装载情况、浮态、初稳性、完整稳型等性能进行校核，包括静水力曲线、稳性横截曲线、静动稳性曲线等相关曲线的绘制，以满足任务书及规范的要求。

五． 螺旋桨设计——设计螺旋桨的直径及其他参数，保证船、机、桨三者的配合，以提高设计船的整体性能。

六．英文翻译——对英文文献《预测渔船在沿海地区的运动响应》进行了翻译并呈现在附录中。

关键词：灯光罩网渔船；主尺度确定；型线变换；性能计算；螺旋桨设计

Abstract

This topic of dissertation is the design of tanker of 65.5m oil fishing vessel .During the design process, the main reference for similar 1000ton as type ship, at the same time，take 《The Standard of Steel Quality Sea-going Ship into Class whit Calculation》 , 《the principle of ship design》，《the construction specification of Steel Marine fishing boat (2015)》，《Jia Fu fishing boat design》etc. as references for design. During the design process, I has considered the ship's speed, maneuverability, economy, performance, etc.

Graduation Project includes the following sections:

First, determine main dimensions – According to the requirements of the task 、 reference book ，consider type ship initially identified the main demensions.Taking the balance of gravity and buoyancy to further determine the principal dimensions, and then checking performance such as volume, speed ,stability and so on.Finally, ultimately determine the principal dimensions of the design ship.

Second. type design -Useing 1-Cp-based law reform typer ship line drawn. Through drawing the water-assisted semi-wide plan to draw the design of ship's water line half-width plan, midship section , outboard profile , in order to get the design of ship-based moulded plan .

Third, general arrangement design - in accordance with the Calculation requirements with reference to the type ship to carry out the design of general arrangement, the main divisions and the superstructure of ships, ship compartment layout and equipment.

Fouth, performance Verification – Considered the loading of the ship design, the floating state, the beginning of stability, integrity , stability and other performance-based verifications, including Hydrostatic curves transversal stability curve, static and dynamic stability curve of the drawn curve, etc., to meet misson requirement and Calculation

Fifth, propeller design – determine the diameter and other parameter of the propellers to ensure that ships, aircraft, propeller with three in order to improve the overall performance of the design of the ship.

Sixth, This part is about the English translation. The translated paper named for Forecasting fishing vessel responses in coastal areas and the version has been presented in the appendix.

Key words：the light attracting failling net fishery(LFN)；principle dimension ；transformation in line ； function calculation ； propeller design；structure design.
