毕业设计论文中文摘要

题目：1500吨浅吃水货船船体结构设计分析

摘 要

本船是1500吨级浅吃水货船，属于无限航区普通货船，可实现江海联运及电机定子、重型机械等大件运输。本设计是以保证该船能够达到所要求的坚固程度为目的，针对该船的主要构件作出强度校核，绘制出结构图与横剖面并进行钢材级造价的估算。

结构强度校核部分，根据钢质海船入级规范（2006）进行计算，先对整体进行校核，然后是局部主要构件的强度校核，从而计算出各个部分的强度要求，选择合适的构件以保证船舶的结构坚固。

根据强度校核，了解基本结构和类型，并设计出基本结构设计书，从而对基本结构与典型横剖面作图。

钢材估算方面，主要采用余量估算方法，对所需钢材进行计算。造价估算方面则对各个单项进行计算，并根据其所占比例，对全船价格进行估计。

本设计中所依据知识，主要来自于规范与相关船舶书籍中。通过本设计对作者所学专业职业知识有了更好的巩固，并为以后的工作有了相应的准备。
