Abstract: To evaluate product manufacturing energy consumption in early design phase and promote energy saving in manufacturing process from the perspective of product design,a correlation model of product manufacturing energy consumption based on design features was proposed.The concept of macrostructure features(spatial relationship and connection mode)and microstructure features(material feature,shape feature,size feature,technical requirement feature)were proposed to express constraint relations between parts,and a product design scheme based on design features was established.The manufacturing energy consumption was divided into direct energy consumption and indirect energy consumption,and the relationships between design features and direct or indirect energy consumption were analyzed.The correlation model and calculating method of product manufacturing energy consumption based on design features were presented.The calculating manufacturing process energy consumption of a gearbox planet carrier was taken as an example to verify the feasibility of proposed method.

Key words: product design features, manufacturing energy consumption, correlation model, conceptual design
