Embodiment Construction

[0036] A quantitative evaluation method for the green performance of a product is to calculate the green performance factors composed of environmental factors, connection relationship factors, structural depth factors, recovery performance factors and energy factors, and perform weighted calculations on each green performance factor to obtain The comprehensive evaluation value is used to evaluate the green performance of the product, as follows:

[0037] Step 1: Disassemble the product. During the dismantling process, select a certain part as the reference component. During the disassembly process, record the number l of parts, the total number of types of connection relationships between parts m, and the quality W of parts. Type n and quality M of materials in parts;

[0038] Step 2: Calculate each green performance factor

[0039] a. Environmental factors

[0040] According to the environmental impact index of product materials, use formula (1) to obtain the environmental ...

Abstract

The invention discloses a quantitative evaluation method for green properties of a product. The green properties of the product comprise an environmental influence property of a product material, a disassembly property of the product, a recycle property of the product and energy utilization rate of the product. The method is characterized in that the green properties of the product conduct comprehensive evaluation through green property factors consisting of an environmental factor, a connection relation factor, a structure depth factor, a recycle property factor and an energy factor, and weighted values corresponding to the green property factors. The method can accurately provide numerical value indexes of the green properties of the product, thereby providing technical support for green design of the product.

Description

technical field [0001] The invention relates to the field of product green design, in particular to a quantitative evaluation method for green performance of products. Background technique [0002] Resources, environment, and population are the three main problems facing human society today, especially environmental problems, which are posing a serious threat to the survival and development of human society. With the worsening of global environmental problems, people pay more and more attention to the research on environmental problems; the environmental performance of materials, whether the product is easy to disassemble and recycle, and the economic value of the product after recycling are several factors that must be considered in the green design of products. aspect. Although designers will consider these factors in the early stage of product design, most products do not have specific quantitative indicators for green performance, resulting in no basis for quantitative ...
