Research And Developement Of Evaluation System For Engineering Materials Selection In Product Design

In view of the problems faced by intelligent material selection and intelligent evaluation in current product intelligent design and research hot spots,this project will study and develop the engineering material selection evaluation system in product design.The system will evaluate the application of engineering materials and the process flow in the manufacturing process based on the product design proposal given by the designer.The overall functional,aesthetic,economical,and green evaluations will help designers Material selection and process optimization in the design process.The research of the project helps to establish a selection evaluation system for materials and processes in the product design of industrial designers,enabling designers to verify the evaluation results of various indicators of the material process in the existing design scheme,thereby better based on the product.The demand and the creativity of its own choose the combination of materials and processes that are more suitable for product manufact uring.Through systematic research on product design and its process,the target and content of product-oriented selection evaluation of product design are determined,and the basic selection evaluation process and system relationship are determined.According to the evaluation of the content of the evaluation system,the system is constructed in three layers: the target layer,the criteria layer,and the target layer.Analytical research and content refinement are made for each aspect,the underlying object parameters are determined,and the product design is finally established.Medium project material selection evaluation system and its hierarchical model.For the four main evaluation directions of functionality,aesthetics,economics,and greenness,because of their respective evaluation goals and content characteristics,a goal-based evaluation classification study was conducted,and based on this,the amplification-based function was determined.The material hardness index screening method and the comprehensive evaluation method of material attributes based on the triangular fuzzy analytic hierarchy process method are used.Based on this,numerical analysis and verification are performed,and the calculation and optimization results are expected.Based on the existing research results,the conceptual design,process design,and module design of the material selection evaluation system were completed and the system development and programming was performed through C#.By dividing the engineering materials commonly used in the design of existing products according to different relevant characteristics,the characteristics of the materials are refined and the characteristics of the materials are integrated.Understand the commonality of features and characteristics of similar or similar material processes,and explore the causes of commonalities and the influencing factors.Combine the relevant content of material process attributes,complete the information modeling and relational integration of material selection evaluation system related databases.The system and the database content were integrated,and the visualization of the evaluation results was analyzed and studied.The design of the interaction mode and the layout of the interface were completed.Finally,using the prototype system to evaluate the material design of the existing 3D printer shell design,and verify the accuracy of the results.
