摘要
面对全球变暖这一严峻的气候变化挑战,减少机床全生命周期的碳排放成为一项至关重要的任务。从设计源头出发,以降低机床全生命周期的碳排放为目标,研究其碳排放特性及其相关设计要素关联关系是机床低碳设计的基础工作。为有助于在早期设计阶段评估机床全生命周期碳足迹,提出一种面向方案设计阶段的基于设计特征的机床全生命周期碳足迹评估方法。提出机床系统特征(关系特征与运行特征)与单体特征(几何特征、技术处理特征、材料特征)的概念,表征机床零部件间层层约束关系,并建立基于设计特征的机床设计方案表达模型。将机床全生命周期内的碳排放活动归类为面向设计特征的六类特征关联活动,建立设计特征与碳排放活动之间的关联机制。提出基于设计特征的碳足迹量化方法,建立机床全生命周期碳足迹评估模型。以计算和分析某锯切机床的全生命周期的碳足迹为例,验证了所提方法的可行性。
In the face of the severe climate change challenge of global warming,reducing carbon emissions throughout the life-cycle of machine tools has become a crucial task.Starting from the design stage,with the goal of reducing carbon emissions throughout the whole life-cycle of machine tools,it is the basic work of low-carbon design of the machine tool to study its carbon emission characteristics and the correlation of its related design elements.To evaluate the carbon footprint of machine tools throughout their life-cycle in the early design stage,a method for assessing the whole life cycle carbon footprint of machine tools based on design features was proposed for the design stage.The concepts of machine tool system features(relationship features and operational features)and individual features(geometric features,technical processing features and material features)were introduced to characterize the hierarchical constraint relationships between machine tool components,and the expression model of machine tool design scheme based on design feature was established.The carbon emissions activities throughout the whole life-cycle of machine tools were classified into six categories of feature-related activities based on design features,and the correlation mechanism between design features and carbon emissions activities was established.A quantification method for carbon footprint based on design features was proposed,and a whole life-cycle carbon footprint assessment model for machine tools was established.The feasibility of the proposed method was verified by calculating and analyzing the carbon footprint of a circular saw blade saw machine throughout its whole life-cycle.
