【摘要】：绿色化是机械工业发展的主要趋势之一。利用结构对称性实现产品绿色需求已经引起人们注意。国内外对机械产品绿色设计和机械对称性分别已有不少研究,然而对利用对称性实现产品绿色需求的研究尚较少见。本文主要研究如何应用结构对称性提高机械的绿色性能,取得了如下的进展:1.基于产品生命周期,初步建立机械绿色设计需求体系,其内容包含节约物料、节约能量、节省时间、环境友好和人类友好等方面。2.基于实例,初步分析了结构对称性在满足产品绿色需求中的作用与效果,提出部分绿色需求-产品结构对称性关联知识。3.基于实例分析,提炼了机械结构对称性-绿色需求的部分关联知识,并提出应用结构对称性满足绿色需求的产品设计方法和流程。4.应用上述方法开展绿色产品实践,获得一项用于能量回收的发电式减速带的发明专利。
[Abstract]:Green is one of the main trends in the development of machinery industry. It has attracted people's attention to realize the green demand of products by using structural symmetry. There have been a lot of researches on green design and mechanical symmetry of mechanical products at home and abroad, but the research on realizing green demand of products by using symmetry is still rare. This paper mainly studies how to apply structural symmetry to improve the green performance of machinery, and makes the following progress: 1. Based on the product life cycle, the requirement system of mechanical green design is established, which includes material saving, energy saving, time saving, environment friendly and human friendly. Based on an example, the function and effect of structural symmetry in meeting the green demand of products are analyzed preliminarily, and a part of green demand-product structure symmetry correlation knowledge. 3 is put forward. Based on the analysis of examples, this paper abstracts some correlative knowledge of the symmetry of mechanical structure and green demand, and puts forward the product design method and flow chart of applying structural symmetry to meet the green demand. Applying the above method to green product practice, the invention patent of power generating speed reducer for energy recovery is obtained.
