Examples of how to select materials for product design

Environmental factors from consumers, competitors, international trade, and domestic and international laws and regulations pose great challenges to businesses. Against this backdrop of pressure, green design has emerged. GreenDesign (GreenDesign) is the environmental performance as the main goal and starting point of product design, has become an advanced design thinking. In the product design stage, the choice of materials is an important part of the decision to achieve the design goals. Therefore, the selection method of green design materials has become an important research content. The material selection of green design requires the selection of materials that have little impact on the ecological environment and make full use of resources and energy as much as possible in product design, i.e., the selection of green materials (Green Material, GM). This paper firstly analyzes and discusses the current research status of material selection methods in green design of products, secondly discusses some basic concepts and characteristics of green design, analyzes the relationship between green design and traditional design, and researches the main contents and key technologies as well as the design principles and design methods of green design; and once again analyzes the Material Lire Cycle Assessment (MLCA) of material selection. Cycle Assessment (MLCA, Material Lire Assessment) of the main content of the material environmental certification standards are discussed, the development of a material environmental certification standards, the purpose is to promote various types of materials researchers, producers and users are concerned about the environmental impact of the production and use of materials, to promote the improvement of the environmental performance of the material, so as to achieve the purpose of protecting the environment; and then, the selection of green material methods Then, in-depth research on the selection method of green materials is carried out, the principle of material selection based on environmental awareness is put forward, various factors of material selection are analyzed, the framework and method of green material selection system based on cost are put forward, and the fuzzy evaluation system of green material selection is constructed on the basis of this; finally, the active spiral bevel gears of the "four-axle main reducer" of the chassis of the WS2400 heavy-duty cross-country vehicle is used as one of the key components of the chassis of the WS2400 model. "Finally, the active spiral bevel gear of WS2400 chassis, which is one of the key components of the chassis, is used as an example for empirical demonstration, and good results are obtained, and this method has certain guiding significance in the actual work. The fuzzy evaluation system of green material selection studied in this paper can feed back the results of the assessment to designers and manufacturers, which is conducive to the design of more environmentally friendly green products.
