船舶栏杆在曲面甲板上的等间隙智能布置

Intelligent Arrangement of Ship Railings with Equal Clearance on Curved Decks

提出一种在艏部曲面甲板上智能布置不同规格复合材料栏杆的方法,包括栏杆规格与数量确定和布置旋转2个步骤。分析栏杆的布置施工要求,列出使栏杆布置最优的目标函数和约束条件,简化栏杆选型、布置和旋转要求,进而完成用于对栏杆进行排列组合的选型矩阵的构建。基于此,结合三维设计软件CATIA实现栏杆自动选型和甲板布置轨迹坐标获取,利用四元数推导并证明模型2次旋转转化为1次旋转的方程,简化栏杆模型在甲板上的旋转流程,最终在CATIA软件中编程,完成复合材料栏杆的自动布置,有效提升栏杆布置和建模的效率和质量。

An approach that intelligently arranges composite material railings of different lengths on the curved deck of bow is proposed,including two steps of determining the railing size and quantity,and arranging the rotations.The selection matrix modeling for railings arrangement is completed by analyzing the construction requirements for railing layout,listing the optimal objective function and constraint conditions for railing layout,simplifying railing selection,layout,and rotation requirements.Based on this,the automatic selection of railings and the acquisition of coordinates on the deck layout trajectory are achieved with the 3D design software CATIA,and the equation for converting the model rotation from twice to once is derived and proven using quaternions,which simplifies the rotation process of the railing model on the deck.Programming of automatic layout of composite material railings is completed with CATIA software,effectively improving the efficiency and quality of railing layout and modeling.
