中文摘要：

能量优化设计方法是一种在设计初始阶段就把节能与功能实现摆在同等重要地位，并在设计全程中给予综合考虑并行推进的产品设计方法。结合公理设计理论，对能量优化设计基本单元“设计元”的内涵进行修正扩展，使其成为设计域之间映射与能效模型的封装体，将设计过程与能量信息紧密结合起来，并使各个设计阶段的信息描述具有了统一样式。在探讨设计元与公理设计理论具有相同的功能映射实现基础之上，联合公理设计理论建立设计元的分解过程模型，用以描述方案的生成过程。创建包含逆向、正向能量设计两大过程的能量优化设计方法。其中，逆向能量设计过程的目的是获取产品的能量设计信息；正向能量设计的目的是在产品能量设计信息的指导下，将功能实现与能量优化联系在一起，获得最优设计方案。最后，以数控车床为对象，对能量优化设计方法的有效性进行了验证。

英文摘要：

Energy optimization design method is a method for the comprehensively considering the energy consuming and function operation of product at the same time during the process of design. Informed by axiomatic design theory, the definition of design unit, as the basic element in the energy optimization design method, is modified and extended to the package of the mapping between design domains and energy efficiency model. The design process and the energy information can be integrated together, and this design information in various design stages can be presented in a uniform expression. Since design unit （DU） and axiomatic design （AD） have the same mapping basic for function realization, the analyzing process model for design unit is established to describe the solution generating process. The energy optimization design method, including reverse and positive energy design process, is established. The energy design information is obtained in reverse energy design process, while the function operation and energy optimization is integrated together in positive energy design process, to get the optimized solution under the guidance of the product＇s energy design information. Numerical control lathe is presented as the case study to validate the energy optimization axiomatic design method.
