[Abstract]:Low carbon product design is a research hot spot driven by low carbon economy. On the basis of summarizing the current research status at home and abroad, this paper puts forward the design and feedback method of product structure regeneration oriented to low carbon. The technology of carbon emission quantization feedback and structural scheme evaluation in the design process is around the multi-layer modeling and structure regeneration technology of product structure. The research and application in the structural design process of several products verify the feasibility of the proposed theory, method and technology.
The organizational structure of the full text is as follows:
The first chapter is a summary of the domestic and foreign research status of the key technology related to the product low carbon design and the product structure design, and points out the shortcomings of the current product low carbon design and the product structure design, and puts forward the main research work and the paper organization structure of the paper.
In the second chapter, a multi-layer integration model of product structure for low carbon design is constructed. The method of improving product low carbon performance by optimizing the structure of each layer is analyzed from various aspects of product structure. The recovery performance of the product is improved through the overall selection of the product layer, and the components are improved by module subdivision and reconfigurable expression. The reusability of the layer structure; the production, assembly and disassembly of the product are improved by the regeneration of the part structure. The corresponding models of each layer structure are established, and a multi-layer integration model of the product structure for low carbon design is constructed.
The third chapter: Based on the structure multi-layer integration model, the product structure regeneration design technology is studied. Based on the product structure and material association model, the product recovery strategy is generated quickly and automatically. The corresponding selection algorithm of the product is put forward. The operation process of module reconstruction is described by the algorithm of directed graph, and the structure of the component is realized. The regenerative rules of the structure are used to regenerate the structure of the part and extract the regenerated related carbon emission information. Taking the actual design problem as an example, the realization process of the structure regeneration design is expounded.
In the fourth chapter, the carbon emission quantitative feedback technology in the process of product structure design is studied. The mapping method of product structure and carbon emission information is put forward, and the carbon emission is quantified by the method of relative carbon emission factors. By tracing the relevant information of various kinds of carbon emission during the life cycle of the basic parts, the basic carbon emission of the enterprise is constructed. Using the function decomposition tree mapping structure, the hierarchical hierarchical division of product structure is formed, and the layer by layer structure and carbon emission information are extracted by layer by layer, and the hierarchical expression of carbon emission in the product is constructed to the bottom, and the carbon emission feedback mechanism in the process of product structure design is put forward, and the product structure is designed to be designed. Real-time carbon emission feedback in the process.
In the fifth chapter, the structure scheme evaluation technology of low carbon analysis of product fusion based on Pan logic reasoning is studied. The propositional expression of product structure scheme is realized with the form of function and or tree and matching propositional set, and the evaluation process is refined by using the independent matching propositions to evaluate the overall integration, and the product performance index is refined. It is divided into functional evaluation index and low carbon evaluation index. It takes the independent matching propositions as units and uses the method of fuzzy comprehensive evaluation to evaluate the effect of the proposition self correlation and interrelationship on the true value of propositions. The general logic reasoning method of compound proposition is used to evaluate the overall structural plan.
The sixth chapter introduces the development of low carbon oriented product structure design system and its application in the design of multi mechanical and electrical products, which verifies the feasibility and effectiveness of the proposed theory, method and technology.
The seventh chapter summarizes the research results and prospects the future research work.
