[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.
