基于骨架模型的船体结构快速建模

A Rapid Structure Modeling Method Based on Skeleton Model in Ship Design

针对当前我国船舶结构设计中迭代次数多、设计存在异地性的问题,提出一种船体结构快速建模方法。以"自顶向下"为设计思路,以骨架模型为实现载体,对船体结构特点进行分析、总结后构建了面向船舶结构的骨架模型,给出船体结构骨架模型的定义。通过船舶结构的骨架模型与参数坐标系实现船舶总体的快速布局设计;建立参数坐标系与船体板架之间的关联关系实现船体结构的快速建模与快速调整,并给出相应算法;给出设计信息的组织方式并将设计信息集成到骨架模型实现船体结构模型的完整性定义与快速建立。最后基于CATIAV6平台开发快速建模系统,并通过纵骨架式船体结构验证了方法的可行性。

Aimed at the problem that there are many iterations in China’s ship structure design and there are different designs in different national regions,a rapid modeling method of hull structure is proposed.The method takes“Top-Down design”as the design idea and the skeleton model as the carrier.After analyzing and summarizing the characteristics of the hull structure,a skeleton model for ship structure is built and the definition of the model is made.The rapid layout design is realized through the skeleton model of the ship structure and the parameter coordinate system.The relationship between the parameter coordinate system and the ship plates is established to achieve the rapid modeling and adjustment of the ship structure,and to give the corresponding algorithm.The organized design information is integrated into the skeleton model in order to realize the integrity definition and rapid modeling for hull structure.Finally,the rapid modeling system is developed based on the CATIA V6 platform,and the feasibility of the method turns out to be verified by the longitudinal skeleton structure.
