[Abstract]:The traditional design methods are characterized by design redundancy, waste of raw materials, unfriendly environment, high cost and long design cycle, which can not meet the requirements of customers for low consumption diversification and enterprises for low cost and high income. Therefore, it is necessary to innovate and correct the existing design methods. Based on axiomatic design and design structure matrix, an adaptive product family configuration method is proposed in this paper, and its application is studied in order to bring customers the best product experience and meet the needs of the market. The main research contents are as follows: 1) the structure and function decomposition of the product is carried out by using axiomatic design theory, the product design matrix is constructed, and the design structure matrix is planned by transforming the design parameters and function requirements. The product design correlation matrix is constructed by analyzing the relation of each parameter, and the product extension cluster analysis is introduced. Finally, the structure and function parameters of slide conveyor are decomposed and mapped, and the design structure matrix is constructed. 2) Product platform planning with adjustable variables based on difference analysis. Based on the axiomatic design and design structure matrix, the customer demand is analyzed, and the product characteristic parameters are extracted, and the product design correlation matrix is constructed. Through the difference degree calculation and clustering analysis of product parameters, the product platform parameters are determined, the common platform variables and adjustable variables are identified, and the product platform planning method based on the difference analysis is put forward. Finally, the feasibility of the hydraulic block brake is verified by using the method as an example. 3) the design of adaptive parameterized product platform is studied. Through the market analysis, the user demand investigation, determined the product each structure parameter, used SolidWorks to carry on the parameterized modeling to the product, selected the design parameter through the priority number principle, determined each design parameter value, The main parameters and follower parameters are determined and the parameterized product platform is finally determined. Taking the wheel set of bridge crane as an example, the application of adaptive parameterized product platform configuration method is studied. 4) after constructing a parameterized product platform based on difference analysis and adaptability oriented, a product family configuration method based on adaptive product platform is proposed. Firstly, the adaptive product platform is introduced, and then the personalization and common parameters are determined, the sensitivity analysis of the product design parameters is made, and the design correlation matrix is constructed to identify the adaptable product platform parameters. The product family configuration based on adaptive product platform is realized. The bridge crane trolley is taken as an example to verify its design. The results show that the feasibility of the adaptive product family configuration method is well verified by the example analysis, and the design method can also be extended to other product design and development. The application of the above design method can meet the diversified demands of customers and help enterprises reduce the design cost, reduce the waste of resources and control environmental pollution.
