摘要： 基于Visual Basic和Access的系统框架，运用知识工程的基本原理，实现了集装箱船舯剖面的结构设计、优化及三维建模. 设计中新船的布置通过对母型船布置形式的拓扑调整获得. 在2条母型船结构参数的基础上，运用插值方法结合规范公式获取新船的构件参数，并对其关键结构采用遗传算法进行参数优化设计，其收敛性良好. 通过与直接规范设计结果的对比表明，该方法兼顾规范和设计经验的要求，设计结果更为合理. 此外，通过Python程序实现了船体舯剖面在Tribon软件中的自动三维建模，大大提高设计结果的人机交互性.

Abstract: As an important target of containership, the midship section can well reflect the transportation ability and containers arrangement, so it has always attracted designers attention. This paper studied the design, optimization and 3 D modeling of midship section based on Visual Basic and Access. The arrangement of the new ship can be got by topology of the motherships . On the basis of structural information of mother ships, the structural information of new ship can by got by interpolation method according to rules formulations, then the genetic algorithm is adopted for optimization of key structures and it converges well. Compared with the design obtained by Rules method, the one by Interpolation method considers both the rules and design experience of experts, so it is more reasonable. Besides, 3D model is built in Tribon by Python program, which enhances manmachine interaction and makes the result easy for designers to modify.

Key words: knowledge based engineering(KBE), midship section, structural design, optimization
