With the continuous transplantation and integration of computer technology and network technology into the field of design and manufacture, computer-aided assembly process planning has become an inevitable trend. In view of the complex process of assembly process design of key parts of diesel engine, the lack of means of process verification and the low efficiency of field operation, this paper analyzes the integration methods of various application systems from the point of view of unified data source. Based on the key technologies of assembly process planning, process simulation and process visualization, the platform of visual assembly process planning system for marine diesel engine is constructed. Promote the development of diesel engine manufacturing enterprise production model to advanced manufacturing direction. The specific research contents are as follows: (1) the 3D assembly process planning technology research based on unified data source is proposed. The product EBOM is received from upstream and the product model library is established. The 3D process resource database is established by combining process resource classification and modeling rules. On the basis of EBOM, the assembly transcoding based on the expression of assembly hierarchy and sequence is combined to generate PBOM. automatically. Detailed 3D structured assembly process planning, dynamic information of all kinds of data sets, integrated process model and assembly process structure tree are developed to provide stable and unique products, resources and process data for downstream process simulation and visualization. Improve the accuracy of data transmission, solve the process data management confusion, process information is not clear and other issues. (2) around the complex product assembly as the core, the digital assembly process simulation technology research, combined with the application system integration, Process planning data are extracted, organized and converted into process simulation data. The digital assembly scene based on simulation is built, and the assembly path planning and simulation based on the key parts is combined with the assembly scene, and the deeper ergonomics simulation analysis is carried out around the human being. Based on the assembly process planning platform, the integrated management of assembly simulation data is carried out, and the problem of lack of reliable verification means for process scheme evaluation is solved. (3) aiming at the fact that the on-site assembly operation guidance is not intuitive, the quality data management is confused. The problem feedback is not timely and so on. This paper puts forward the field oriented assembly process visualization technology research, combined with network technology and application system integration method, to create a field oriented process information, resource visualization platform, Considering the demand of field quality data management and process problem feedback, the paper puts forward the paperless management mode of field quality data, establishes the communication bridge of field problem feedback, and achieves the purpose of "not disjointing" between field operation and process design. (4) based on the above theoretical analysis, this paper combines Teamcenter and Vis MockUp software to independently apply and develop the integrated link between process planning and process simulation. Combined with the network technology, the visual platform of assembly process oriented to the field is built, which is convenient for operators to carry out visual operations, quality data management and process execution feedback, so as to get through the key links of process planning and field manufacturing in collaborative environment.
