【摘要】：随着现代船舶的日趋庞大与复杂,船舶舾装工艺已演变为一项综合性的系统工程。作为舾装工艺的关键环节,舾装件装配规划串联着舾装工艺的设计与现场舾装件的装配施工,其水平直接决定了舾装件的装配质量和效率。然而当今舾装件装配工艺规划主要依赖工艺师的专业知识与经验,缺少高效的数字化验证工具,这在一定程度上制约了舾装工艺的创新和转型。虚拟装配技术可为舾装件装配规划难题提供有效的解决方案,是信息技术融入到船舶制造业中的重要体现。依靠虚拟装配技术,工程师可在设计阶段对虚拟环境中舾装件的整个装配过程进行仿真模拟,规划出合理、可行的装配方案。因此在虚拟环境中深入研究舾装件装配规划技术,对于提高舾装工艺的装配水平,降低施工成本,改善工人的劳动环境及促进舾装工艺的升级具有很大的指导意义。本文以某油船机舱底部的区域性单元预舾装工艺作为装配规划的研究对象,主要研究内容及方法如下:(1)系统地介绍了舾装工艺的内涵及类型,阐述了现代造船模式下区域舾装法的施工流程,并重点总结了船舶机舱底部区域舾装件的装配特点及方法。(2)分析了虚拟装配技术下装配信息模型的特点,利用CATIA软件对机舱区域的船体、舾装件、舾装场地进行三维建模,随即导入到DELMIA_DPM软件中搭建虚拟装配环境。(3)提出了基于遗传算法规划舾装单元吊装序列的方法。在规划吊装序列的过程中考虑了舾装单元的装配连贯性、最短移动路径以及重要资源的利用率,并在这相互制约的三项工艺中计算出了最优的吊装序列。(4)在DELMIA_DPM虚拟环境中对舾装单元的整个吊装过程进行了仿真模拟,并基于包围盒法和机械公差原理在仿真过程中检测出发生干涉的舾装件,进而规划出合理可行的吊装路径和装配计划。(5)在DELMIA_DPM虚拟环境中对船舶机舱底部区域工人的装配过程进行了仿真模拟,并基于人机工程技术对整个装配过程进行了分析。最后使用模糊综合评价法从人机工程的角度对该区域舾装件的可装配性进行了评价。
[Abstract]:With the increasing size and complexity of modern ships, ship outfitting technology has evolved into a comprehensive system engineering, as a key link in the outfitting process. Outfitting assembly planning series outfitting process design and field outfitting assembly construction. Its level directly determines the assembly quality and efficiency of outfitting. However, nowadays the assembly process planning of outfitting mainly depends on the professional knowledge and experience of the craftsman, and lacks efficient digital verification tools. This restricts the innovation and transformation of outfitting technology to a certain extent. Virtual assembly technology can provide an effective solution for outfitting assembly planning problems. It is an important embodiment of the integration of information technology into the shipbuilding industry. Depending on the virtual assembly technology, engineers can simulate the whole assembly process of outfitting parts in the virtual environment in the design stage, and plan out reasonable. Therefore, in the virtual environment, the research of outfitting assembly planning technology can improve the assembly level of outfitting process and reduce the construction cost. It is of great significance to improve the working environment of workers and promote the upgrading of outfitting process. This paper takes the regional unit pre-outfitting process at the bottom of the engine room of a tanker as the research object of assembly planning. The main research contents and methods are as follows: (1) the connotation and types of outfitting technology are introduced systematically, and the construction process of regional outfitting method under modern shipbuilding mode is expounded. The assembly characteristics and methods of the outfitting in the bottom area of the ship engine room are summarized emphatically. The characteristics of the assembly information model under the virtual assembly technology are analyzed, and the hull of the engine room area is analyzed by using the CATIA software. Outfitting, outfitting site for 3D modeling. Import into DELMIA_DPM software to build virtual assembly environment. The method of planning outfitting unit hoisting sequence based on genetic algorithm is proposed, and the assembly continuity of outfitting unit is considered in the process of planning outfitting unit. The shortest mobile path and the utilization of important resources. The optimal hoisting sequence of the outfitting unit is calculated in the three mutually restricted processes. The simulation of the whole outfitting process is carried out in the DELMIA_DPM virtual environment. Based on the bounding box method and the mechanical tolerance principle, the outfitting components are detected in the simulation process. Then the reasonable and feasible hoisting path and assembly plan. 5) in the DELMIA_DPM virtual environment, the assembly process of the workers in the bottom area of the ship engine room is simulated. The whole assembly process is analyzed based on ergonomics. Finally, the assemblability of outfitting parts in this area is evaluated from the point of view of ergonomics by using fuzzy comprehensive evaluation method.
