摘　　要：在大数据、网络化环境中,设计人员无法有效地利用海量的机电产品设计信息与数据来应对当前机电产品全生命周期下绿色设计需求。针对这一问题,提出了基于生命周期性能关联的绿色设计知识表达及获取方法。首先建立基于操作-产品-性能(OPP)的基本关联构型,提出面向生命周期下绿色设计需求的绿色设计知识表达,并提出该结构内各元素的规范化表达;然后利用同义词林和相似度分析对设计信息及数据进行标注处理,构建基于OPP构型的基础关联词典,提出基于绿色关联度的绿色设计知识获取方法;最后,结合机电产品中液压阀零件实例验证所提方法的有效性。研究结果可实现绿色设计知识的多层次多粒度表达和有效获取,为机电产品全生命周期绿色设计实际应用提供基础方法支撑。In the environments of big data and networking,designers could not effectively utilize the massive information and data of electromechanical product design to meet the demands of green design in the whole life cycle of electromechanical products.To solve this problem,a method of green design knowledge expression and acquisition was proposed based on lifecycle performance association.Firstly,the basic operation-product-performance(OPP) relational architecture was established,and the green design knowledge expression oriented to the requirements of green design in life cycle was proposed,and the normalized expression of each element in the structure was proposed.Secondly,synonym forest and similarity analysis were used to annotate the design information and data,and a basic association dictionary was constructed based on OPP architecture.A green design knowledge acquisition method was proposed based on green association degree.Finally,an example of hydraulic valve parts in electromechanical products was given to verify the validity of the proposed green design knowledge expression and acquisition method.The results may realize multi-level and multi-granularity expression and effective acquisition of green design knowledge,and provide basic method support for the practical applications of green design in the whole life cycle of electromechanical products.
