[Abstract]:SEN2101 boiler feedwater pump is one of the main components of CAP1400 nuclear power station. Its working environment is harsh and changeable, and its components are various (including 93 main functional parts). At the same time, the internal structure of the feed pump is extremely complex, there are many flow phenomena, such as flow separation, secondary flow and so on. The performance requirements of feedwater pump itself and the characteristics of nuclear power industry put forward higher requirements for the function and reliability of SEN2101 type feedwater pump, which increased the difficulty of research and development. The modeling of new product development process based on DSM (Design Structure Matrix, design structure matrix takes full account of the space, energy, information, material and so on among the parts in the process of complex product design. It can effectively reduce the number of design iterations caused by the close connection of parts, shorten the product design cycle and ensure the quality of product design. In this paper, DSM theory is introduced, and the dependence of variables in complex products is clearly expressed by matrix form, and the DSM model of feed pump parts based on DSM theory is constructed. Through the module clustering method in DSM, the corresponding clustering of feed pump parts is carried out, and the connection in the structure of feed pump product is analyzed. Through the two-step mapping of BOM process DSM in part DSM process, the research and development process model of feed water pump is presented, and the optimization scheme is put forward. According to the optimization scheme, through the three-dimensional flow field analysis and rotor dynamics analysis, the design process of feed pump is shortened effectively, the quality of product design is guaranteed, and the simulation analysis of product and cluster design flow is carried out. The optimized scheme is evaluated, and the effectiveness of the DSM model in optimizing the design process of feedwater pump is verified.
