| While the manufacturing industry of our country especially high-end equipmentmanufacturing industry develops at a high speed, it is facing huge pressure of carbon emission.Setting energy-saving and emission-reduction as the target, the research of low carbon designmethod is proposed from the very begining of product design t’o consider products low carbonemission character and other design information, which is the need of in-depth work carried out inlow carbon technology in manufacturing equipment. With the support of National Natural ScienceFoundation key projects, taking forging machine as study object, this paper gives an in-depthstudy of carbon footprint calculation, analysis and low carbon design mapping method. The mainwork is as follows:The calculation process for carbon footprint of forging machine tool is firstly established. Onthe basis of studying calculation criterion of product carbon footprint, this calculation method forproduct carbon footprint based on the factors of carbon emission is applied to forging machine too1. Then an uncertainty and sensitivity analysis is given in the calculation result, which comprehensively analyzes the life cycle carbon emission of forging machine tool.On the basis of function analysis for forging machine tool, the structure model of low carbonproduct of the forging machine tool is set and carbon footprint of module unit is calculated and allocated, combining product carbon footprintanalysis and function-structure mapping together, which effectively achieve the carbon footprint separation of function-structure. The carbon flow modeland quantitative analysis model of main carbon emission links for forging machine tool in the usephase is established, which provides low carbon parameters extraction with the modeling foundation. Carbon footprint factors of forging machine tool in the use phase are identified, and low-carbon improvement technical measures are proposed from the aspects of design, control optimization,use and technique.Secondly the concept of low carbon design mapping is put forward. The model of low carbondesign mapping is established based on three views of the function layer, structure layer andparameters layer. The extraction and decoupling method of the key low carbon design parametersfor forging machine tool is researched deeply. On the basis of the acquisition and analysis of lowcarbon demand and low carbon design requirements, product requirements of low carbon designare mapped to function structure unit in each level and the low carbon design parameters based onquality function deployment for environment, which provide the mapping information foundationwith the low carbon design scheme.Finally Combining traditional product design process,the process and system for low-carbondesign reuse method of forging machine tool based on multi-hierarchy mapping isestablished.Low-carbon design cases in each hierarchy are represented by extensionmatter-element, and are classified by clustering algorithm. The similar low-carbon design casesare retrieved in conformity with low-carbon design request based on case by reasoning. Theindicator system of low-carbon efficiency for forging machine tool is established. The reuse schemes are devised to reuse the present knowledge of low-carbon design for forging machinetool. |
