Mid-ship Section Structural Design and Optimization Based on Knowledge Based Engineering

Abstract

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
