【摘要】 船舶机舱管路布置是目前所有规划设计中最为复杂的布置问题之一。在狭小的机舱环境中离散分布着大量形状复杂的组件及设备,舱壁、组件和设备间又相互影响,构成管路的障碍。同时管路布置必须满足各种各样的设计约束,如安全性、经济性、生产加工和维修保养等方面的要求。目前船舶管路设计仍然要依赖设计者的经验用人工的方法来完成,因而,实现管路自动布置是缩短设计时间,降低设计成本,保证有效设计的关键之一。在这样背景下,本文提出一种基于仿真的船舶机舱管路三维自动布置方法,主要研究内容包括：(1)在研究文献基础上,对船舶管路布置所应遵循的规则进行收集、汇总、分析、总结和归纳。(2)采用完整信息模型的表达方法,经过对目标场景进行分割和对设备模型合理简化,快速构建目标场景,并使场景和模型最小化,以便于后续算法的实现；在构建仿真设计环境时,引入自由空间建模方法,以解决与操作或维修空间有关的约束建模问题。(3)设计吊桥算法和二次穿越算法,以适应在管路布置中使用自由空间建模方法；设计路径模板,并分别给出了分层布置和分区布置的路径模式；对路径的评价目标进行的描述,并在算法中加入管路对布置空间影响的成本修正系数。(4)最后,根据提出的方法,应用CAD软件作为程序开发平台,利用VBA技术编制程序。以一艘实船的布置环境为目标,实现自动布置,给出设计结果,并与船舶的实际布置进行比较,用来验证算法的应用效果。经过与实际船舶布置情况对比,利用本文所提方法得到的管路连接路径节点等设计数据比较可靠,方法正确、可行。该方法以船舶设计实际为研究的出发点,与当前船舶设计的实践联系紧密。更多还原

【Abstract】 Pipe route design of ship is one of the most complex planning and design task. There are billions of complex-shaped components and equipment scattered in a small engine room. Walls, equipment and components are obstacles of pipes and interacts each other. Routing of pipes should meet various design constraints or requirements for physical, economic, safety, production, operational and maintenance, etc. This process is done by hand in practice rely on the experience of the designer. Achieve the automatic plan of piping is considered as the key element for reducing design time, cutting construction cost and ensuring effective solution. For the above reasons, a method for simulation-based 3D pipe-routing automatic plan of ship engine room is proposed. The main study included:1. Based on literature research, the rules for pipe route design of ship are collected, analyzed and inducted.2. To minimize and rapid construct the simulation scene of arrangement by using the representation of information-completed models, the objective scene is divided into small modules and models of obstacles are simplified. At the same time, free space modeling method is introduced to processing constraints relevant to operation and maintenance space.3. Hanging bridge algorithm and re-cross algorithm are proposed as the solution for pipe-routing arrangements using free spaces models. Path patterns of pipe for layered or blocked layout are planned respectively according to special rules. A factor is presented to evaluate the spatial effect of pipe-routing.4. Finally, use CAD system as a programming platform, an example based on real ship environment is given to validate the approach by comparing the obtained planning with the actual design of the ship.Comparison results show that the proposed method is correct and effective; the data of connecting nodes of piping design is reliable. The proposed approach is closely related to the facts of current ship design.更多还原
