【摘要】 船舶市场的国际竞争愈来愈激烈，由于传统的船舶设计方法已不能满足现代船舶设计的需要，近年来船舶设计中引用了计算机技术，使设计计算工作大大简化。海船设计已引入了不少国外软件，但是在军船和内河船设计中还大量使用AutoCAD软件，国外的海船设计软件通过DXF文件也可以同AutoCAD软件相通。所以通过AutoCAD软件平台对船舶结构图进行数据处理，从而智能化分析船舶结构几何、物理等参数的研究，这无论是对船舶设计，还是对船舶结构动、静强度计算都具有重要意义。 本文就是基于此目的，通过船舶设计图形的数字化研究，实现船舶振动预报数据输入的智能化。采用了以VBA为工具，进行AutoCAD的二次开发的方法，并将此方法用于船体结构的AutoCAD图纸研究。 为了用B样条曲线描述船舶线型，本文首先介绍了其最关键的内容，即B样条曲线插值程序设计原理。其次对船舶结构的构件和板分别进行参数识别，然后将所有数据分模块录入事先建立好的参数化的数据库，为计算船舶振动预报有关参数的智能化处理提供了良好的前提。最后编制了“船舶振动预报数据输入”的智能化软件，该软件以AutoCAD为平台，由船舶结构图替代了大量的人工数据输入，最终完成船舶振动预报，该软件输入数据与人工数据输入进行了验证。 本文所得到的软件具有通用性，能够适用于任何一艘船舶的AutoCAD结构图。更多还原

【Abstract】 The traditional ship design method could not meet the demand of the modern ship design and the ship market competition is more and more intensified. In these years, the design and calculation work are simplified as the computer technology has applied to the ship design. Many kinds of foreign software have been applied to the sea boat design, but the AutoCAD is still largely used by the warship and keel ship design. The foreign design software can be connected with the AutoCAD by the DXF document. To analyze the geometrical and physical parameter of the ship structure is apparently important to the ship dynamics and static’s calculation by dealing with the ship structure data under the AutoCAD IDE.This paper is based on it to realize the intelligentized data input of the ship vibration prediction by studying the digital of the ship drawing. VBA is selected as tool to develop AutoCAD. And this method is applied to the AutoCAD drawing research of ship structure.This paper introduces the most key knowledge, namely the program principle of the B- spline curve first in order to use it to characterize the ship shape. Then parameterized recognizes the components and planes of the ship structure. The data gained will be put into the module database built beforehand which prepared for the ship vibration prediction. The intelligentized program of the ship vibration prediction data input is completed at last. This program substitutes the manpower data input based on AutoCAD. And the vibration prediction is entirely completed up to now. On the other hand, the program is verified in the process of the application.The program can be commonly used to the AutoCAD drawing of any type of ship.更多还原
